I've had a problem the last month or so with the battery going dead and the car not being able to start.
I've checked the battery for a dead cell (new battery Delco 5/06), checked alt for bad diode and charging,it's good.I had a load test on the battery, good.
Checked for "draw" on battery and it shows very little.
I can drive car for 2-3 days no problem starting. Short trips never a problem, only when it sits for extended period of time, say 6 hours or more, but NOT all the time.
Anyone had a problem like this with a 94 FW or have an idea where to start looking?????

TIA :confused:

If it's checking out fine, then how is it dead?

I was having lots of weird slow start and once or twice no start issues with my '95, and after the battery checked out fine, I finally realized that the cable bolts attached to it were old and nasty and kept getting loose. Replaced those, and haven't had a nick of a problem yet.

But yours does sound a bit different--still worth checking, though (if you haven't already). Otherwise, there's a lot of different things it could be.

Hi....No, I've checked, tightened all the connections, nothing loose.
I'm just wondering if this problem is common or someone has experienced the same thing and can give me a clue on where to start.
Thx

How much of a draw is a little draw? Give us numbers. You know cold weather and batteries dont mix. But I still wanna kmow what your draw numbers were...

What about your load leveler pump? Is it running a lot? Leak in your shocks and/or air lines will cause the pump to run more than it should. Might be pulling your battery down.

load leveler pump....removed, replaced the air shocks with Severe duty shocks.............

Thanks for the ideas....

I have had a very similar problem with the DTS and it ended up being the starter. I could go days with no problems, then got more and more frequent. It had all the simptons of a dead battery, but then after trying several times or sitting for a few moments, it would turn over.

Had an intermittant 'drainer' for about a year on a Corvair. Seemed to be worse the colder it got. Left wife stranded several 0 to -10 mornings getting off work.

You know those aircooled rigs basically used a HD dryer hose for pass. comp. heat. It turns out a mech. finally found a spiral wire there had frayed to the batt. term. on the starter, (absolutely perfectly 100% not visible from below) and it touched more with cold weather. It had to travel all the way up the spiral to the hoseclamp and the plenum shroud.
:mad:

Short point being it's either something obvious as posted by others above, or, a gremlin from hell that makes you want to get the 24-hour cooling off period over with at the gunshop so's you can shoot the mf'er to death right NOW!

Sorry, doesn't count. Buy dielectric grease, buy a good wire brush. Completely disconnect each end of each wire in the starting circuit under the hood. If you're lucky, something will jump out at you. Hint: They sell just that replacement funny sidepost bolt.

Did you do ANY mods recently? Not just electrical either. You need to give us the mA drain readings.

Trunk lights are often culprits if the car is on any incline. Or if the holder is bent it can do it.

Is the RAP turning off? Retained Accessory Power might be sticking on...

Hi....I'm getting it narrowed down. I had a problem today with it and I'm thinking the negative battery cable is corroded inside the casing !!!??

How does that happen????????

I'll keep everyone posted

Thx for all the advice

For the first couple weeks after I got the car, my battery would randomly drain when I parked it. It didn't always happen, but there were a few times when I parked it during school and came out to the car and it wouldn't start. The problem just fixed itself after awhile. I dunno what the deal was.

Fixed the problem, 99% sure!!!!

Here's one to remember, The POWER antennae....took the car to an electrical specialist yesterday. I had the draw .250 ma narrowed down to one circuit. The circuit that turns on your interior lights when you touch the outside door handle. Remove that fuse and the draw went .025 ma, thought I was on the right track (fuse#38). Also the circuit for my car alar, so I thought the circuit board in the alarm was screwed.
He checks it and tells me it takes 10 minutes for the pcm to go to "sleep" mode, he unhooks everything, visor lights power ant,etc that is STILL on after you turn off the ignition.
He plays with this and finds the antenna draws almost 3 amps to retract, it's been so cold up here, the antenna wasn't retracting all the way and not shutting off the limit switch with was cycling causing the draw............. :D
I'm a little happier now.
Thx for all the help.

That's wierd. My antenna often also may not go all the way down (1 1/2" to 1/2" from bottomed) most recently during some icestorms, but with no negative effects.

I can hear the ant. trying to retract, and after several cycles it just stops and does not sound as though it's still trying anymore.

You think you might have a bad ant. anyway? I replaced mine 3 years ago.

Glad you found it -- maybe. Are you going to leave it up motor disconnected to test it?

Word: WD-40. Mine was full of black crap all up and down :cool:
