Ok, I was working on the horn issue and let that go. The cig lighter does not work either. HAve checked all fuses before - 2 mo ago, changed out horn relay, etc. Anyhow. I printed some advise for cig lighter/ aux fuses etc. Got out tester. Now, the one thing is the battery is under the back seat in this car. So i took tester there and then checked out those fuses. All is well. It is a pain having to get a spare battery or moving another car up to check the front ones. The spare battery is dead, so pulled my lincoln up , checked out tester after putting it on battery, go to the Buick,,,, and NOT ONE fuse will test in the front of that car! I am not any idiot, I know how to use the tester! Talk about a waste of a day!

what are you trying to do with another battery? if the cig lighter circuit isnt working you need to follow along the diagram to where you stop having power

trying to test all of the fuses under the hood.

you dont need another battery to test fuses. most of them have the metal exposed on top now so if you just put your black lead on a good ground and test both sides for power you know its good. if one side doesnt have power its blown. if one or both sides is flakey or intermitant the fuse socket needs cleaned

ok, will tell him, this is wife.... NONE of the fuses would light witch is definately stupid.... or is he??lol

if he is using a test light which isnt good because you need to see the number. because alot of the problems with newer cars is the fuse connection itself. the ground he was using for the tester was likely no good. as a matter of practice you should always be in the habbit of testing a known good voltage like the positive side of the battery or something else you know works on your car.

He tried the tester on his car which was there for battery use. it orked fine. But when tried in same place for ground to my car, nothing at all lights up. Cannot use our battery , it is under the back seat. He is trying to test under hood fuses. Works fine on back ones using battery.

you can use a part of the engine for ground normally, just scuff it up a bit. and the big red wire on the alt should have power

Using a remote battery and a ground on the car to check fuses is a sure fire way to blow some (or all) of the fuses. Pull each fuse and use your meter to do a continuity check between each terminal.

fianlly got it to work, all fuses good. GAve up. Goiing to put toggle on the horn after talking to inspection station to verify it is legal in Nh, so both issues taken care of except cig lighter issue which is not in fuses so will be looking further, thanks.
