ive been working on a delorean getting it running after sitting, it ran several times and shut off as normal but recently when i went to start it i used a jump starter to boost battery power and now the ignition switch does not shut off the car as normal.
it will start and run and the electrical systems function normally, but now when the ignition switch is turned off most electrical systems(radio, center console) will turn off as normal except for the engine will continue running and the dash lights and instruments still operate despite the ignition being switched off and even the key being removed from the ignition. from there the car must be shut off by removing battery power, the dash and engine will of course shut off and will stay off and when battery power is restored the dash lights will NOT be on with ignition off as one would expect but when the car is started the process will start again.
to sum it up the ignition switch will function normally turning the cars systems on but is not properly shutting the car off, the dash and engine remain powered.
can anyone with better understanding of the delorean electrical system help me fix this problem and lead me into the right direction?
my hypothesis is that the jump starter(50 amp boost supposedly) damaged either the ignition switch or a relay related to the ignition switch
thankyou
