I've got a F350 chassis on an RV. The chassis battery keeps draining and than won't take a charge ( the battery goes bad) Have replace 3 in 3 years, last 1 lasted 2 months.

I did find a drain with a test light between negitive post and cable. the test light does not stay on it fades out in 1-2 secounds. It is a 40 amp fuse for (courtesy light relay contacts,cluster memory,BB battery feed) i don't know what these things really are, or if this is normal. I'm I barking up the wrong tree!

Thanks
