What do you have that's like an ignition switch? Yes, the fuel pump will be fed with a switched live but also will be killed by the inertia switch and might have something unusual if it's controlled by the ECU. The bit I would be most concerned about with wiring it that way is drawing too much current. This might blow a fuse or ask the wire to carry too much current. What's the model or part number of the alternator? Jonathan
Not sure... what will happen to thos of us who have those tyres already fitted come the date in question ?? I asked the manufacturer and a supplier about this and got quick, straight answers. Jonathan
4 ancient Michelin Pilot tyres, 185/60R14, 2 about 2mm tread, 2 about 5mm tread. Don't know why anyone would want them. Available soon, South Oxfordshire. Jonathan
Disconnect the feed and then measure the voltage (above earth) at the end of the lead. With the lead disconnected measure the resistance from the sender terminal to earth. And how full is the tank? Jonathan
But it wasn't meant as a sarcastic comment on searching... it was about the number of people who must have done exactly the same as "your colleague". ;-) Jonathan
There was a post about 21's a little while back and from memory they will still be produced but that they will no longer be E marked. Yes, link posted earlier in this thread. Jonathan
There's a wiring diagram in the archives. Why do you want one... racing cut-off or avoiding drain while it's unused? Do you need an immobiliser? Any chance of it living on a conditioning charger? Jonathan
I think that failure on searching (and possibly success) should return the search term(s) as editable text in the search field. Not a high priority. Jonathan
That's all you need to know. The potentiometer (or whatever*) needs to offer the same resistance. If you do the test with the gauge still in the car and using the car's battery don't forget to use a fused feed. Jonathan * For your purposes you could do this with a few fixed resistors.
