Marc Posted February 16, 2017 Report Share Posted February 16, 2017 I've taken all the advice given on this site and the last one given was to check the wires running down the driver side of the engine and see if they were melted. I did that and none were melted. I am still having the problem of my 87 505 stx 2.8 liter Peugeot only when the key in in the off position the windows and heater/air conditioner fan works only when the dome light is in the on position also, i have know power going to the fuel pump fuses behind the ashtray. Someone said that it might be the main computer but, the car starts and runs if i run a hot wire from the fuel pump to the battery. This all started after i installed a rebuilt Delco starter. Would it be possible to run a dionostic test on it at this point at a local auto repair shop and this run down the ground problem or do i need to take it to a forien car repair shop. All i know is that at the power plug in terminals by the battery the double plug-in that i think goes to the ignition switch also, when unplugged turns off the dome light, heater ect., so is this a good place to start dionostic testing and it it possible that a rebuilt starter can cause such ground problems?

Goce Posted February 17, 2017 Report Share Posted February 17, 2017 Any willing mechanic or electrician can diagnose problem like that, it would help him and you if you source a wire diagram for the car, the trick this days is to find a willing mechanic.

Bean Posted February 19, 2017 Report Share Posted February 19, 2017 Power is feeding the circuit either by a shorted wire or through bad grounds. There is no other explanation, and it can't because of the starter unless you messed the ground wire to block. You mention that the interior light is connected to the issue - if the light is off that turns off power to the windows with key off? If so the fuse circuit the interior light is on is feeding the windows / fan circuit. If that's the case you need to isolate the circuits and find how the two are connecting - my guess is the ground. It's quite easy to diagnose if you know DC circuit theory - So find someone willing to tackle it. It being a Peugeot should not scare anyone smart - so count it a blessing if they don't want to work on it because it's a Peugeot. Make sure to only use someone goos though because a hack can do a lot of damage. Rabin Quote Link to comment Share on other sites More sharing options...
