300 electrical problem

509 Views 9 Replies 5 Participants Last post by  stevev
I've had an on going electrical issue with my 300 for quite a while now. I'm getting a build up of this white powdery stuff around the battery box area. About every 6 months I take everything apart and clean it up, cable connections, ground strap,etc. Battery acid level is good, seems to be charging okay, 12.5 v.
Any ideas?

Thanks all, I'll check your suggestions.
Thanks, I did a very thorough cleaning and painted all corroded areas. Battery is charging fine. 12.5v, and 14v right after starting engine. Drops down to about 13.2v after running for 1/2 hour. Then when it rests overnight, back down to 12.5v. Guess time will tell.
Steve - any update on this issue?
Seems to be okay right now. No sign of acid venting or the white build up associated with that. Still a little soon to be sure,but so far so good.
