Hi there,
My truck's ('71 Series IIa, EX-MOD) battery will discharge after about a 1 to 2 weeks if left off trickle charger or not run regularly. I have tracked the issue down to a 0.07 amp current drain that is coming from the blinker and flasher circuit. When I bring that circuit online, I can hear the Hella 4DM001 863 relay click on and it begins to draw a small amount of current. Is this normal? I cannot find any specs on the unit from Hella themselves. I would think it is not normal.
Maybe it is an aftermarket addition to add the Emergency Flashers when it was converted from MOD to Street Legal and mis-wired? The Fuse box is a Lucas but has 4 fuses, which does not seem to match what the manuals wiring diagrams describe as just a two fuse circuit.
Here is a photo of the unit.
