TomGaval Posted April 16, 2003 Share Posted April 16, 2003 Weather finally warmed up and I was able to take the se7en out for a nice blat for the first time since November. Started right up, ran great, but, the turn signals now do not work. They worked fine the last time I had it out. Any ideas where to start looking? Thanks in advance.

Andrew Dent Posted April 16, 2003 Share Posted April 16, 2003 Could well be rust. Check all earth points and make sure you have continuity in the earth line. I had this and it ended up being corrosion on a washer stopping the earth line working. Andrew does it hurt when you hit 40? Link to comment Share on other sites More sharing options...
Terry Field Posted April 16, 2003 Share Posted April 16, 2003 What 7 version? On my crossflow there is a junction box taped to the upper chassis just inboard of the front wheel. It is a rubber block and the end terminals just push into it. I had the same problem as you, and found that it was just a bad fit into the box. You will need to check the wiring diagram to pick out the right couloured wire. Terry Trying to get out of the garage Link to comment Share on other sites More sharing options...
Sheds Moderator Posted April 16, 2003 Share Posted April 16, 2003 I had this on my 1.4 kss. It was a bad connection to the ind relay which is under the dash on the passenger side. The passenger's knees bash it regularly and loosen the connectors. It will be sth like this or corrosion of connectors. They have a bad time on 7s, exposed spades under the wheelarches don't help. Thanks caterham. Link to comment Share on other sites More sharing options...
allegro Posted April 16, 2003 Share Posted April 16, 2003 I've had this before. Switch on and off the hazards. That fixed mine. Andy Mac C7 GON 😬 Team Langoustine. Hard Core Prawn here 😬 Link to comment Share on other sites More sharing options...
Meldrew Posted April 16, 2003 Share Posted April 16, 2003 Second the hazards advice. It happened to me a while ago and I found that clicking the hazards on & off reset everything. According to Simon Lambert, "they all do that, sir". Link to comment Share on other sites More sharing options...
old captain slow Posted April 16, 2003 Share Posted April 16, 2003 3rd the hazards. Any electrical problem always fiddle with that first! C7 CDW Link to comment Share on other sites More sharing options...
julians Posted April 16, 2003 Share Posted April 16, 2003 I had this and it was the indicator switch itself, it had corroded. Took it apart and cleaned it up, it works fine now. Link to comment Share on other sites More sharing options...
Chris W Posted April 16, 2003 Share Posted April 16, 2003 Tom If none of the indicators are working, it's less likely to be an earth problem because the 4 indicators are individually earthed and therefore all 4 earth points would have had to corrode. Not impossible of course but unlikely. I would suggest looking at points, that control all four indicators, which may be corroded or have a loose connection. These are: (i) check fuse 12 (10A) which supplies power to the flasher unit. (ii) the indicator switch itself (iii) the flasher unit under the dash (iv) the indicator relay under the dash Suggest you remove the latter two and reinsert in their holders. (v) the hazard relay and flasher relay share a common earth which bolts to a stud on the wiper motor. Check this lead (black) is OK. What happens when you switch on the hazard switch - anything or nothing? Hope this helps Chris 1.8K SV 140hp see it here Link to comment Share on other sites More sharing options...
Dartmoor7 Posted April 16, 2003 Share Posted April 16, 2003 If the indicators don't work but the hazards do, the problem is almost certainly in the hazard switch. Click it on and off a few times - usually sorts it. Also had this on two tintops in the past.

TomGaval Posted April 23, 2003 Author Share Posted April 23, 2003 Thanks for the replys guys. I moved this past week and am still without internet access at home. Back at work, and I'm able to check in on Blatchat. Withdrawl is painfull. Current situation, no indicators at all front or back, all lights work, when hazards switched on all indicators work. flipped hazard switch on and off several times, checked that the indicator switch terminals were tight, still no indicators. I'll check the fuse and relay tonight. Any other suggestions. Thanks, Tom Link to comment Share on other sites More sharing options...
Graeme Smith Posted April 23, 2003 Share Posted April 23, 2003 Try flicking the hazard switch and the indicator switch a few dozen (rather than just a couple of) times, to clean up the connections. Link to comment Share on other sites More sharing options...
Sheds Moderator Posted April 23, 2003 Share Posted April 23, 2003 On my old Cav if the indicators packed up the cure was to turn on the hazards then pull the switch G E N T L Y out with wiggling. It would then switch off easily and the indicators would work for the next 3 months. Some of the MoT testers used to do this for me if it did it during the test... They all do that Sir. Prob. sth. similar will fix yours. If not, new hazard switch Link to comment Share on other sites More sharing options...
Chris W Posted April 23, 2003 Share Posted April 23, 2003 Tom If the hazard function works, but the indicators don't, there can't be anything wrong with the flasher unit, the earths, the wiring to the lamps or the lamps themselves. It clearly must be something that controls only the indicators. Therefore, it could be the hazard switch of course but I suspect the so-called "hazard relay" (as it's known in the car manual) which is actually an "indicator relay". The relay is ON all the time the ignition is ON and supplies the power from the flasher unit to the indicators through the indicator switch. This relay is used solely to ensure the indicators are ignition dependent so they can't be accidentally left on. The hazard switch bypasses this relay in hazard mode so the ignition doesn't have to be on. Try taking this relay out - on my K it's the second one up from the bottom - and reinserting it. If things still don't work, try taking out one of the other 2 relays - they're all the same type - (horn or headlamps but not the flasher which looks physically different to the others) and plugging it into the hazard relay slot. If things work, you've found the problem - dicky relay. Try also putting the hazard relay into the headlamp or horn slot to ensure as a further test that relay is working or not. If the hazard relay is OK but things still don't work indicator wise, it has to be the hazard switch or the indicator switch. Bridging the contacts on the indicator switch with a screwdriver blade (centre contact to one of the outside contacts) will tell you if the switch is malfunctioning or not. Can you swop out the hazard switch with anyone just to try it? Or you can also test the hazard switch in isolation - see my post today to Mike E's "Hazard warning light toggle switch" query. Basically it's just a question of applying good engineering logic and eliminating the offending beast by substitution or test. good luck Chris 1.8K SV 140hp see it here Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted April 23, 2003 Leadership Team Share Posted April 23, 2003 When this problem occurs it is most often caused by the hazard switch. Rather than flicking the hazards on/off, quite firmly push the switch in (or into) the off position - usually sorts the problem. Mine cut out everytime the hazard switch is used - the return mustn't be very positive. Stu. Link to comment Share on other sites More sharing options...
TomGaval Posted April 23, 2003 Author Share Posted April 23, 2003 Chris and Stu, I'll work on it tonite when I get home. I know its been said before, but this site has to be THE BEST interms of responsiveness, and competency of the the posters. I like most of you found the build manual lacking. But with the help of alot of fellow blatchatters, I got the beast built and running, and terrorizing the neighborhood. I made it to Stoneleigh & Cadwell last year. Can't this year. Will in 04. Thanks again. Tom Link to comment Share on other sites More sharing options...
JP Posted April 23, 2003 Share Posted April 23, 2003 I second batteredoldsup... - I've had the same problem and after fiddling with swicthes and checking fuses, all that was required to remove, clean and replace (not renew) the relays.

Chris W Posted April 23, 2003 Share Posted April 23, 2003 None of us can be that definitive............ It'll turn out to be what it turns out to be............ all we can do is carry out the right tests to identify the problem.... and fix it... hopefully in a way that it doesn't re-occur..... too soon. I prefer to go through things methodically and logically where car electrics are concerned. Otherwise, we accidentally fix the problem and don't really understand why it suddenly starts working again cos we're aren't sure what we were wiggling at the time.

Englishmaninwales Posted April 24, 2003 Share Posted April 24, 2003 Indicator problem is due to corrosion in hazard switch. New switch results in 100% reliability (until that corrodes!) Malcolm Link to comment Share on other sites More sharing options...
TomGaval Posted April 24, 2003 Author Share Posted April 24, 2003 Update, turn indicators now functioning. After repeated flicking of both hazard and signal switch, and finding that the relay appeared to be kicked loose, they now work. Big thanks to all.
