HA, and if you wash your ride, it's even better

But seriously, now that you have your eye on electrical, one re-occurring process seems to be the key to continued reliable operations.

SO many problems, those which are occasional and others which are "in your face", occur from marginal to bad Grounds. The smart operator will set a schedule (once every year or two*) to go through the entire system, remove/clean thoroughly/replace tightly, all of the grounds, both of the high amperage circuits, and others which exist around the vehicle.

*= Highly depends on which region one lives in, States like...
New Mexico/Arizona - less frequent,
Gulf/lots of rain - more frequently,
Northern/salting roads - yearly, possibly with a good pressure wash underneath,
