Ignition Stays On Even If Key Position Is Off

[Munkyb0y]

Hey guys. This only started recently.

If i switch ignition on, but dont start the car, and then turn the key to off, even remove it, the igniton lights stay on.

I have to then start the car, and then switch it off for it to behave normally.

Because i dont usually switch the ignition on without starting the car, i'm not that fussed. but I thought if some knows what it is...possibly a suspect relay or something easy, I could sort it out.

Cheers

so what alarm is in it?

[Munkyb0y]

mongoose m80

oh and it's probably important to mention. the first time this happened was when my battery went totally flat, and i couldnt crank the car over, i was just getting that click click. i turned the key to off position to go grab jumper leads, and the ignition lights stayed on. had never seen it before then.

it has a new battery now, and cranking perfectly.

reprogram the alarm. I dare say it was spiked when you jumped it off.

[Munkyb0y]

how do i reprogram the alarm?

and the igniton lights stayed on, BEFORE the jump start. Just to clear that up.

If its a Mongoose M80 I then it may be related to the state of the door circuit, call me for further explanation, it will save me writing up a 2 page explanation.

[Munkyb0y]

haha, you installed the alarm years ago when i first bought the car.

will call you tomorrow at a decent hour.

i think its the m80au

thanks for your help over the phone leon.

i checked out all the relays and found the problem.

it was a previous modification, whereby the aircon relay is connected to the rad fan relay via a one way diode, which switches the thermo fan on everytime aircon is on. THREAD HERE

when i put it back to stock, the igniton behaved normally.

why is that happening? possibly the diode i used? (1N5404 which is 400V 3A)

what's another way to wire up that fan so it comes on with aircon? coz i can certainly notice an improvement in aircon with it wired up.

cheers
