Whats wrong with my fusebox circuit :/
Turbo Mini Forums

Hey guys,

So I managed to track my fault (engine not cutting out after I remove key) down to the circuit that powers my Aux fusebox, as everything stays on now till I manage to kill it.

I have drawn up my circuit below:



I cant see whats going wrong here. The perm live comes form the pole on the inertia starter solenoid that the battery cable goes to. When I finally manage to kill the engine the circuit then turns off and everything looses power.

The fusebox (not the aux fusebox) on the diagram is the one under the bonnett on the bulkhead and is exactly as you look at it.

Cheers

have you got a fluke at all? What you need to do is run your engine and switch it off. So your run on occurs or what ever and then do resistance checks to see if there is a short some where in the circuit, your looking for low resistance when you should get OL. Or check for voltage and see if a voltage is still getting across anywhere. Sorry if its a crap answer if i was there id help, but diagrams aint my strongest point.

could you have a dodgy relay?

Done now needs redoing lol

maybe? I thought that but wouldnt it make the aux fusebox live permanetly?

I used this relay previously for my spot lights. I have a spare so will give it a god and see what happens.

Any other ideas guys?

do what i said. Wait for the fault to occure and pull out the fluke and test the relay to see if its still being energised or is sticking.

With the fault happening, i.e. engine continuing to run after you've turned the key off, what happens if you disconnect the wire that goes between your original fuse box and terminal 86 on your relay? Does the engine stop?

Whats a fluke hazpalmer?

Neil, I turn the engine off pull the key out and the whole aux fusebox is still live. I will try and pull the connection off of the fusebox/pin 86 and will see what hap

Cheers guys

Okay got hte got running turned key off, nothing happened as usual unplugged the spade off of the fusebox and it killed it straight away.

Im guessing that means I have this connected to the wrong pin?

I would say that is permanent live, not ignition switched. Test it with a multimeter or a bulb on a wire.

oaky, managed to trace it back to the inertia solenoid. I unplugged the altenator and then the relay worked exactly as it should of. I put the perm live on the brass pole on the inertia starter underneath the main battery cable, was I meant to connect this elsewhere?

On the left of it is white/pink and white and underneath it is green

I found that with the altenator unplugged it works as it should

Yes it does mate

speed didn't kill me, but taxation probably will

Hello mate sorry its a bit late, i will do this tomorrow. If this happens then what have I wired wrong haha

It was a circuit i made to have an aux fusebox only run when the ign was live or when the car was cranking, as the pin on the lower fusebox provides this I used it for my relay

Label the drawing and explain what you are trying to achieve. As that drawing makes no sense to me, as the relay will always be energised assuming the lower fuse box is always live

If the fuse output you have chosen does go off/on with ignition, then what you have shown there should work.

And you should fuse the wire from the solenoid to the relay to protect that wiring.

i cant quite make out whats happening?

does the engine start and stop on the key with the alternator un plugged?

but keeps running when the alternator is pluged in?

sounds like the alternator is feeding your relay somehow

Yes i moved to the darkside

Yes Brett thats whats happening. Im going to try the thing with the brake lights like Neil said above and will post back later on

Okay I start the engine, turn the key off it carries on running Ign light comes on, Press the brake pedal and the engine stops, but the ign light doesnt come back on?

I recall Andy (apbellamy) having the exact same issue on the upside down skip? I can't recall what he said about it though, sorry.

Hopefully he'll see this thread, but you could PM him also.

Ok thanks carl, I have messaged him on fb
