Topic: Current leakage (Read 1240 times) previous topic - next topic

Anyone have a current leakage problem of battery discharge with all electrical consuming equipment off and disconnect switch off?

What vehicle are we talking about?
Not all electrical devices  go thru the shut off switch.
The Carbo Monoxide & Propane Detectors are wired directly to the batteries.
If you have a solenoid operated propane shut off valve, that also is wired direct.
These are called Phantom draws.

Just about every car nowadays has some sort of after current or after voltage when the keys turned off just to keep the computers and things monitoring. The only way I know of to get rid of the leakage is to disconnect batteries or get Battery Tender to maintain it. I did the later.

My 2021 Unity TB has between 35 and 48 watts being consumed when not in use or ready for storage.

I have a Victron shunt 500A on the coach batteries - when I turn the main switch off and the propane solenoid off it reports no draw and reports if the solar panels are charging the batteries.
for the chassis starter battery using the Battery Isolation Cable by the gas pedal to disconnect for long storage periods has not draw for the earlier years but then MB added and auxiliary battery under the seat that has a draw which can be eliminated by pulling fuse #32.  My 6 yrs old battery is still good after 4 months which included a hard winter of -15C days in January.
