Thanks, you're right, I've always carried jumper cables since I grew up pre-cell phone
. And no one should plug in to their TV while its engine is running. But I'm confused about a PUP's power circuit. I thought the 7-way plug supplied power to the converter box--when being towed, converter box doesn't really convert anything it just sends TV power to energize the 12V system running lights (wait, it does send a 2v or so trickle charge to the battery).
Anyway, if winch is powered by the 12V system (and not straight from battery), winch's draw is always thru converter box regardless of where its
power's coming from (shore power, TV or battery). Now logic tells me if the battery's dead, I could power up the converter box/12v circuit by either TV or shore. Winch's power draw goes thru the same wiring and fuses any which way, and no component's ever smelled funny or blown no matter which way I've powered the converter box. Weird things happen with electricity though. I've rambled long enuf, thanks for correcting any erroneous thoughts or agreeing or telling me I'm all wet
