Any ideas where to start looking for this problem?
Engine starts on the key fine, but if you remove the key while it's running the engine carries on running. Tested the ECU ignition live wire and get the following:
Ign off 0v
Ign on 12v
Engine started/running 14v
Ign off 14v
Could be a slight connection problem behind the hazard switch as i had this problem but wasn't constant
D'oh just sorted it, a relay was sticking causing the ECU ign live to keep 12v.
That was quick for finding a sticky relay, you can look at my diesel if you like lol
I told him to do it.
Alex didn't help at all :)
Hmm this is still happening. It worked fine when I bypassed the relay, however I have fitted a new relay and it is happening again.
Basically I have an existing ignition live feeding a relay. The relay input is a fused positive and output is to my ECU ignition live.
Key out 0v, ignition on 12v, key out back to 0v
However when its running it doesn't go back to 0v when the key is removed
wtf?
Got to be something do with the alternator id guess with it staying powered once the engine is running.
Whys your ignition live wired through a relay anyway?
Hes got it so there is one perm live coming in, switched by a existing ign live, and then running lots of things off that one relay, so no worry about load.
Which is fair enough, But I wouldn't run the ecu ign supply like that.
correct relays being used?
