I share your dilemma, Yrmac, but think it would be wise to go ahead with replacement. It seems to me that after about 125% of the warranty period, you are on "thin ice". Don't you agree that the cost of the hassle associated with a failed battery is likely to be greater than the ~$65 for a good replacement? Of course, if you have standard shift, and can thus bump-start the car, you are slightly less vulnerable than with an auto transmission.

Elec Problem with 97 Explorer XLT by eaglejim

My Explorer has an intermitant problem. The pwr windows, pwr moonroof, interior lights, & windshield wipers all stop working.Used to occur once a week, now 2-5 times per day. Sometimes, turning motor off & re-starting will fix problem. Sometimes, hitting a pot hole will fix. Dealer just charged me $85.00 to tighten the ground wire on the GEM mudule. Could the GEM module be bad? How about the key swich? I'm lost as to where to go. Not sure dealer knows how to fix.

There is a list of part numbers for this TSB, if you want them, e-mail me. Click on my name and it will show my e-mail.
One of the mentioned relays is likely the problem, whether it be the relay itself or the connector.

I tried to email you for the part numbers for this TSB, but it would not go through. I really appreciate your help. My dealer told me there were no TSB's for this problem. I Have an appointment on Monday with a different dealer. I will show them your response to my problem. Hope they can fix before the snow starts to fly. Thanks Again.

Electrical trouble by mcaldron1

I have a 1986 Honda Accord with 257,000 miles on it. It has started to have intermittent electrical problems like:
* Lights flicker when brakes are applied
* Dashboard door open indicators activate randomly - no doors are open
* Brake light failure indicator light comes on intermittently - all brake lights work fine
 
The car has been very reliable, and I would like to fix this somehow. Any suggestions? Thanks!!

257,000 miles? Probably cardiovascular problems associated with old age. Seriously, the door-open indicator-lamp is likely to be associated with one of the door switches that's worn or out of adjustment. With the engine running, crack each door open very slightly and see if one door causes the light to come on just as the door begins to open. The flickering when the brakes are applied could possibly be associated with a short in the brake/tail light assemblies. When it is dark, have someone activate the brakes, turn signals, and tail-lights while you watch carefully to see that they work OK and that each bulb has the same light intensity as its counterpart on the other side. If there are any right-to-left differences, a corroded bulb-socket is likely to be the problem. These ideas may not help but they are easy to do and could lead you to the problem source.

grungy grounds by swschrad

sour grounds are often a point of failure that affect multiple systems. unfortunately, the ground point for systems F, Q, X, Y, and AA7 are often some distance away from any logical point the circuits would go to. fixing them is pretty easy, remove the nut and associated spade lugs and lock/toothed washers, clean up any oxidation or corrosion or reterminate the wire involved and replace the hardware, coat all parts lightly with grease, and reassemble tightly. finding them is not easy without a manual -- even the Haynes/Chilton series will often have enough of an electrical diagram to find the most likely grounding point. I really marked up and dirtied the manuals for my Mopars, Buick, and Ranger.

Brake lights by edchen

I have a 1988 Acura Integra LS. The brakes lights have shorted out or something and won't turn off. This is causing the battery to rundown very fast. I've the pulled the fuse and it uses less than 25ma so the brake light seems to be the only problem. Any ideas where I should go from here?

Start by checking the brake light switch adjustment. It's usually on the brake pedal support bracket. The plunger should be fully depressed when the pedal's in the released position.
