Not stumped, your just not using a volt meter to do any testing,
to see where your so called power is not going

Also you have to look further into any fuses,fuseable links that may be open.

The only way I work on any vehicle, is to have a wiring diagram

That way you start at the battery & walk down every circuit that may
apply to the problem,TESTING as you go

What you have is an open circuit-- you have to find

1996 Volvo 850. No electrical power.


You may have a bad positive battery cable, with a digital volt meter you can test and see if you are getting 12 volts through the entire cable or at least to the cable junction block, in or by fuse relay center, then check cable from there to starter. you should also check the main, battery, power, fuses and relays, usually in the under hood relay center(fuse box)

I resently did work on my 97 gmc jimmy and took out the battery. when in got done and put the battery back nothing worked. no lights no radio no nothing. now my battery was charged and theres power going...


It's a cable issue. What type of work did you do? Anyway there are two cables coming from positive terminal, one straight to battery one to pdc (fuse block) gm has poor set up there clean retighten not too tight. Or during your work a ground was left loose or undone. Security not the problem. Turn on headlights wiggle either cable till they flicker thats where problem lies.

Where is the starter relay in 97 oldsmobile aurora


In a '97 model car most of your relays would be in the power distribution box by the battery, but very seldom that is the problem. Truthfully, without a multi-meter and some electrical systems understanding, you would just be looking in the dark. But having checked your battery connections-both cables are snug and tight on a new, fully charged battery? And the new starter had its mounting bolts down tight and, most important, the electrical connections (large battery cable end, and the small starter solenoid wire) all put back in place and tightened down?

Well, if you got it all back together right, turning the key to crank should send voltage to the small wire on the starter solenoid, energizing it and allowing battery voltage to pass to the starter motor and thus crank the engine over. If you have a problem with the starter, that's where you start looking=at the starter. Check if the small wire has power in start position of the ignition switch. Cheery-o's!

1996 cadillac seville electrical system dead try to start no electrical power


Hello: Check the battery and cables for excessive corrosion, remove cables from battery, clean cables, remove small bolts from cables and clean or replace them make sure they are tight when re-installing. Make sure the battery is good and fully charged.

Starts at times but not at others. maybe a theft deterent problem?I it started like 8 times consecutively and now all electrical works but no crank or anything.


Try this keep your headlights on and crank starter. Do lights go out?Dash too? If your battery is fully charged it is most likely your srarter motor ,if clicking then selonoid. A starter is a motor with brushes that wear out just like any motor.Try to see if a jump start cranks the motor,if so then your battery doesn't have enough cranking amps to start.Also clean battery posts cables make sure all are tight including grounds.Good luck.
