Can someone tell me how to check whether my charging circuit is working on
this old Merc? I ran a little test on the rectifier which indicated it was
bad and have just replaced it. Now, if I check voltage across one of the
batteries, with engine off, it measured 12.3 volts. With engine running it
went slowly up to 12.7. I thought it ought to get close to 14? Thanks in
advance.
