I just got a voltmeter on the battery and it is reading 5.6 volts. So the problem is not the switch. Either the battery has failed (it's a one-year old "new" Yuasa out of an industrial lighting system), or there is something about hooking up a small gel cell to a large AGM that isn't a good thing

Mike, I used to drive a Pontiac station wagon with a diesel... and two regular automotive-sized batteries connected in parallel. A good system, it gave the cranking capacity needed, but if you should do anything to "unbalance" the battery capacity, (such as try to help by jumpstarting anoth
