97 subaru outback legacy intermitent electrical problem

120K miles, replaced alternator and battery 3 monthes ago, just replaced battery again, was told it was "bad". driving along, can turn on wipers full speed and they will go slower then the slow speed, and a short time later they will be back to nornmal. before the battery was replaced the 2nd ime, it died 3 times and had to be jumped, same symptons as the alternator crashing, radio will die, then car dies. when i have it jumped, i turn key and it clicks, after jump works great. i think something is draining it or the computer is bad, or voltage regulator...please, i am baffled, any suggestions?

I would have all the grounds checked. Sounds like it is not grounding properly. This will in turn not allow the battery to charge correctly and will make other electrical devices to operate incorrectly. For example the body ground if not good it will try to find another ground IE the shift cable. This is not designed to maintain a connection of amperage and will allow battery to die. Also will cause problem with cable and could fatigue it enough to break. Just check for good grounds on motor and body. Hope this helps. Good Luck.

If the groung was glowing, check for corrosion on terminals and inside wire were it was glowing. If you find any it would be best to replace the ground wire with new.

Check to make sure that you have a goo ground by putting a volt meter on the positive battery terminal and the negative on a manifold or some other metal object in engine compartment. You should get battery voltage. It not you know for sure that the ground it bad.

Loud Lifter possibly stuck! Help please!!


The ticking lifter on the Loyale is a common problem. There's a small o-ring between the cam tower and the head that, after so many hundreds of thousands of miles, would "fail" (not to a dangerous point) and the lifters would be partially starved of oil. It's not THAT serious... they can go hundreds of thousands of more miles like that. If you replace that o-ring, replace it with a spring reinforced ring so it doesn't fail. Those can be found at wwwdotthepartsbindotcom. As for the Legacy... those early 2.5s were cruddy. I've seen alot of them throw rods, lock up WAY before they should have. Best bet would be to replace it with a slightly underpowered but bullet-proof early model Legacy EJ22 or go with a newer EJ25. I would just go with the 2.2L.
