Crappy Wiring?

sounds like we are living in a parallel universe. You may have seen this already. If you still have the reel you can remove the slip rings and still keep your current cable connection but have the reel wind up the cable. This is what I did in the project below. My reel was internally badly melted and fused so required extra work. But it yours just has the slip rings and brushes damaged it isn't much work to build the power wind up portion. There is also a project on adding a $6 speed controller to wind down the maniacal speed.https://safaritoonces.org/project-tree- ... gn-change/

The reel was discarded long ago and I haven't missed it. Maybe again in the future, but it's not in my top 50 list of things to accomplish with this coach.

I reviewed the installation guide for the Magnum inverter/charger the RV shop installed, which is a 2812. The cabling spec is 4/0 for runs up to five feet; beyond that, it calls for dual 4/0 cables (is that 8/0?). The cables currently in the coach are single 4/0. Since the coach spends >90% of its time plugged into AC power whether parked at home or at an RV site, the Magnum mostly just maintains the house batteries for the 12 VDC loads. I do have the battery monitoring kit add-on installed, so even with the long cable runs the full voltage/amperage parameters specified in the stored profile are seen at the batteries while charging.

Brian,

Correct. Larger cables are only important if the inverter is asked to provide higher end of its "inverted" amp range.
