Re: BACKUP CONTROL UNIT NEEDED
Stating the obvious, unless the problem is actually coming from the reverser control internals, you have a slight ground on the hot leg of one of the many pheripheral circuits attached to the reverser control unit.
With electricals, it's always 'divide & conquer'. If it were me, I'd be looking for a chafed wiring at stress points like corners & pinch-points. That may be tough to trace wiring that heads off to multiple points, so I'd also be looking at an item closest to the pavement (think: corrosion). That would perhaps be the sidestand, whose circuit ties into the reverser controler.
If you've the time & patience, you could put an ammeter in series with the +battery term & using lowest amp setting, see if you can see the current drain. Better yet, try to get in series with just the hot wire that powers the reverser controller itself, so that other ordinary parasitic drain items are excluded.
At that point, one could disconnect one suspect circuit at a time & see if there's a difference.
But, I would give a good inspection at the sidestand switch looking for corrosion or any damage to wiring, allowing moisture in.
Another thought is to simply disconnect the reverser controler for 48 hrs & verify whether the batt still discharged. Divide & conquer.
