"It's a 2 year old 310R SV." Shared fuse for wipers and washer, as you say. No relay unit. Jonathan

"Do they have an intermittent feature. On my '98 car you flick the wiper switch on-off-on in quick succession to get intermittent. In a particularly heavy downpour, and unaware of this feature I was swearing alot. Ignition off and it resets." More please, Ian: Did that fail in the downpour by the wipers not working at all until you had cycled the ignition? Thanks Jonathan PS: This "feature" caused an interesting diversion for a few hours during my build... trying to work out why the wipers were on while the switch was OFF.

What model of Seven and type of switch? Do you have a multimeter? And would you like a wiring diagram? Thanks Jonathan

Please could someone scan the current collection of fastener packs so that they can be added to the library. Thanks Jonathan

Redline as above, or Caterham Parts. Jonathan

Email sent. Is this all within the headlight bowl? Do you have a multimeter? Jonathan

You're not alone: "Search facility", includes my preferred method... ... click the second link in my Signature below, and add search terms according to taste. Jonathan

I can't find anything in the archives on this type of shift light units. (There's some useful documentation on how to calibrate ACES systems on Sevens, but that isn't the current problem.) Jonathan

Any oscilloscopes near Southwold? : - ) Jonathan

Tools and access. Jonathan

Discussion from 2021, might include a solution... Jonathan

Thanks, James. It would be interesting to see what's on the tacho signal. Where are you, Bob? I'll have a look in the archives. Jonathan

If you send me a Private Message with your email address I'll send you the wiring diagram for the 420. Jonathan

Subsequent discussion of winged Dzus fasteners, including size and source. Jonathan

As a fellow victim of the ratchet trap... ... there are two types of ratchet spanner. The problem only occurs with the type where you turn the spanner over to go the other way! With the type that has a lever you flick the lever and send the key stub back homeward to think again. : - ) Happy New Year Jonathan

Well done. Happy New Year Jonathan

Thanks. Upper bit: self-grip wench, or two nuts as you suggest. Lower bit: self-grip wench Assistance: soak in penetrating oil, as already done, NOT ordinary WD-40, and if that doesn't work then local heat on the female end of the adaptor. Then tonk with a mallet and confidence that it will work this time! Jonathan

Photo, please. Jonathan

Are there any little grub screws? Jonathan

Mazda FL22 long life coolant is based on ethylene glycol and is supplied premixed as "55% coolant, 45% water". I'd guess that any difference from traditional coolants is in the inhibitors rather than the bulk coolant. Jonathan

On manufacturers using it as original coolant: 1 This would have enormous marketing value. Some members of my family used to own Decosol, and getting their products used as part of original equipment was a major objective. Some of you will have bought new cars with packets thrown in. 2 Manufacturers have the capacity to study some of the claimed effects such as reduced local overheating and reduced corrosion. 3 The only example of promotion by a major manufacturer that I can recall for Evans Waterless Coolant was Honda with sone offroad vehicles. That will be in the archives somewhere. IIRC there was the usual lack of evidence. 4 "Some manufacturers are using Evans like coolants: Mazda is using a long life coolant, able to stand 200.000 km or 11 years for the MX5 NC (FL22 engine). This coolant can't be mixed with another one (like Evans)." Thanks. I'll have a look. Jonathan

I'd give a straight answer if I could. Are they GKN Tripode joints? Start here. Happy Christmas Jonathan PS: "Driveshaft rebuild" by Tim Pollard.
