My engine batt goes dead over time when connected up....when disconnected ......no problem.......I think I have traced the problem to the rectifier? diode ? isolater?....that finned device on the firewall with three electrical connections on it. My service manuals call it a diode. I can't find any working explanations in the manuals On this list I read where, with engine running ,there are voltages that can be measured. I measured these with different meters and the numbers are ..top 14.3v....middle erratic from 2 to 13 ,,,bottom nothing......Are these devices available at any auto parts or rv parts place?....are there different ratings for them.....hope someone will tell me what they can....thanks....brian 77 ele 455
