Batteries are very run down. Let's see you have 220 amp hours (Roughly) and likely need to feed 'em between 100 and 150.. that should take at least 4-6 hours then top 'em off for another 4 hours
I'd say you need to measure voltage out at the terminals on teh PD-9245 as either
1: It is not putting out as it should -or-
2: There is a bad wire/connection or solenoid somewhere -or-
3: You have the batteries DISCONNECTED -or-
4: Circuit breaker of fuse tripped/blown
In the event of an EVEN numbered option your test light is your friend
Starting at the battery
Touch clip to one (Most negative) post tip to the Other (most positive) Light should be dim at that voltage .if it is bright the problem is a bad meter.
Now move clip to ground (Any unpainted metal part which you reasonably expect to be ground) still dim.. Good
Now move out along the positive wire.. IF you find a device test both terminals. if it's 4 terminals the two big ones. DIM DIM not the problem DIM BRIGHT (plugged in) or DIM/Dark (NOT plugged in) Problem found.
But start at the converter It has a pair of 30 amp fuses if Im not mistaken and when replacing they must both be replaced together. UNPLUG FIRST then wait a few for the internal filters to discharge then replace both fuses and plug back in
You can use the test light to check 'em by hookign the clip to the BLACK or negative wire on the converter's 12 volt side and touching the tip to both of the small metal squares in the Windows on the blade fuses. Should both give same result. Different results = blown fuse.
