hi, wonder if anyone can help. i own a 1973 camper and when left standing the battery goes flat. i know the dynamo is working as i have had it tested, i've been told that something is 'going to earth' and this is causing the battery to drain to the point that i have now ruined two battery's in 2 weeks!!!!! if anyone can shed any light on my problem pls let me know, thanks.

 

what is a dynamo?
