Seems that the more I fix things, the more I discover more things that need fixing.
I'm sure that never happens to anyone else.
1953 MGTD. Battery fully charged at 13.1 volts.
I've got ignition disconnected while I do compression tests; plugs removed, engine is easy to turn.
This morning I tested all four cylinders. No problems with starter at all. Battery had gone from 13.1 volts to 12.6 volts during the test.
But this afternoon, after recharging the battery back to 13.1, I tried the tests again. First cylinder, starter spun nice and strong, no problems. But second cylnder, I hit the starter button, starter immediately spins nice and strong for about one second - but then immediately slows and turns very slowly.
Release starter button, starter stops turning. Battery has gone from 13.1 to 12.8 volts.
Repeat - same thing.
Is this a failing solenoid? failing starter? failing battery?
I even tried this with a second battery in parallel. Same result.
Thanks.
