Car Forum / Volvo Cars / July 200488 740 GLE Sedan - Will not start after radio install
A friend installed a radio in my 88 740. Noticed that the battery was dead next morning. Took the radio out. Battery went stone dead overnight. Bought a new battery ( other was 6 years old) Car will not start. Can smell fuel, but no fire. Checked all fuses in the dash. OK Any help is appreciated. >A friend installed a radio in my 88 740.

Did he connect power using the original connector or did he connect to a wire from the ignition switch, and did you break a connection when you took the radio back out.

Reinstalled the original. The wierd thing was when I put on the brakes hard the door chime would go off. The car had a antitheft switch installed at one time. What circuit is normally broken to keep the car from starting. It's an auto so there is no clutch circuit. Any other common circuits to break? Thanks. >www.sounds-pa.com | www.thecomputerworkshop.com > The car had a antitheft switch installed at one time. What circuit is > normally broken to keep the car from starting.

This depends how secure the person that fitted the switch wanted it to be, on my 740 I've used an electronic immobiliser to interfere with some power and signal wires going to the engine management brain, also the starter circuit is connected to my car alarm, normally it doesn't turn if the alarm is armed/disconnected, but this can be defeated with 3 slightly healthy braincells and a chunky screwdriver on the starter solenoid, if this is done to mine it turns, but as with yours, there is abolutely no spark. You will have to trace which wires have been messed with, but it is quite possible that they were near the radio somewhere, so you could have disturbed them. Sorry I can't help more, Ken > Thanks. > > >www.sounds-pa.com | www.thecomputerworkshop.com >>A friend installed a radio in my 88 740. Noticed that the battery was >>dead next morning.

Two radios used the factory connector without problems. The third with an internal CD had a problem when I hooked it to the connector - blown fuses and other weird electrical things happening. Turns out that it was the ground connection in the connector. When I grounded it directly to the chassis, all problems immediately disappeared. But when I tried to use the ground in the connector - I had all kinds of electrical issues. I suspect that the new radio had a floating ground ? that was the cause of the problems. |
