I took a look at the archives and have not found a clear answer to my question which is.
Do I have to disconnect the positive and negative lead from the engine to my house batteries in order to check to see if there is a charge coming from the engine alternate.
To put this another way if I put a voltmeter on to my house batteries before the engine is started,,, and they are charged,, I believe it should read 12 .7 or something like that. Now my question is,,, if I start the motor will the voltage jump because the engine/alternator is sending (if the system is working properly) juice to the house batteries.
Not that disconnecting the batteries is such a big deal,,, but it would be nice if I could simply put a voltmeter to the batteries and when the engine started I would be able to tell if the system is sending juice.
I hope I made my question clear???
Thanks for any help
