Managed to get the engine started using the dual battery switch .. then put a meter on the solenoid positive and ground ...meter read 10.8v ...revved up the engine, no difference in reading ...kept engine going for a few minutes and battery meter voltage slowly started to decrease. With headlights on voltage dropped further.

Took battery out, put it on charge for about 15 mins, came up/recovered normally.

I diagnosed this as an alternator problem, could it be anything else?

TIA
