i have electrical issues, went to start the car the other day, it started to turn over, then stopped after a second, lost power to everything, checked fuses, blown one, so replaced it, still nothing is working, now ive checked power to everything, and all the switchs, and fuses have power, but nothing works at all, whats the next thing to check? or what should i be doing to sort it? thanks al

i dont think it has one, its just on a kill switch and push button start, its not the battery its reading 12.6 volts

Check all your earth's - particularly the main ignition cables from engine and chassis to battery. Only takes a loose / dirty connection here and it will kill the lot


will do, ive had enough for tonight, but before i left, my engine to chassis earth had 5 volts, which is not good i presume, the car had been sat out in all weathers for 2 years so i the earth may not be as good as they were

Ignition Relay?

5 volts on earth is definately not good

i carnt find an ignition relay, ill have another look though

This sounds exactly like the problem I have with my R1 indy at the moment. Was turning over Ok, then nothing at all through the ignition circuit. Im sorry I cant offer any help, but will be interested to find out what solves it for you.

im sure its an earth issue, going to redo all the earth tomorrow, and check engine over, as at moment im gettin 12v live through the engine when it should be earth, although it changes all the time so something is wrong

Check the main battery connections.

Both live and earth -all the way through.

If they are loose/slightly corrorded they act lile you describe - start delivering power and then absolutlely zippo.

Clean them all up is my advice.

chassis at 5 V ?!?!?!

how did you measure this?

if you palce one leat on battery negative terminal and other on chassis and see 5 V, then the lead from battery to chassis is making poor contact.

remove leads, clean the termainls with find wet n dry and refit.

that is from engine block to chassis, battery earth is fine, my switchs for ecu, and fuel pump have 12 volts, but there not working if that makes sense

redone engine earth today, but im still picking a live from it, so the engine is getting power from somewhere but not sure where, infact even the throttle cable is 12 v too,

I think you need to explain how you are measuring the voltages you are getting.
If you ARE getting +12 volts between the throttle cable and earth then there is something far wrong. I'd initially disconnect the alternator cables ( and insulate them as the power is on) and see if the voltage goes away. if it does then perhaps some shagged diodes in the alternator.

im testing it with a volt metre on the engine mount, or any part of the engine, i think ive narrowed it down to the throttle bodies, the car never had any issue before, but my engine i run the alternator in a differnt place to what it had before, and the inlet manifold is touching the alternator very slightly and im thinking this is where the issue is, that would make sence wouldnt it?
