Battery banks - possible short?
Hello! I'm looking at getting something to keep the engine battery charged, since apparently the older RV's like mine (30' 1995 Winnebago Adventurer with a Chevy engine) have a drain on them. I found ...

Are you trying to measure resistance in the circuit? That doesn't work; the voltages present confuse the meter. Many multimeters can be damaged if you apply too much voltage to them in resistance mode--and too much isn't always a huge amount. Some good ones have quite robust input circuitry, and there has been at least once that I've been very thankful to have one in that category (a Fluke 73).
As others have said, even out of circuit it's generally troublesome to measure resistance of active semiconductor devices. As the term semiconductor implies, they conduct or not based on comparatively complex relationships, and generally do not act as plain resistors.
Since you see different voltages on either side, it's not shorted. You should be good to go.
