What shop manual are you talking about.
The ones " Bombardier" I have only talk to checking the items but donot have a sequence/logic for checking out each item.
If there is one that speaks to "Checking out the regulator, step one, using a VOM, put the positive(red) prob on the redwire at reg. put the step two, black wire on ------ you should read------ohms" This is what I am looking for.
If the thing isn't running you can not check if it is charging or not.
