Finally got our 1972 clubman back onto the road after 18 years, but I’ve got one issue left to solve. The alternator isn’t providing any charge to the battery!
Alternator light is on the dash, I’ve cleaned up all the earth points and connections, fan belt is new and tensioned correctly, I’ve tried with the original alternator and 2 replacements bought from minispares… all do the same thing.
Question: if the alt plug is disconnected, I can see 12v thru the igniter wire when ground to engine and ignition on. When the igniter wire is connected to the (all 3 of!) alternator, it is only showing 1.5v…. Is this normal?
I’m guessing not as I’d expect that 12v to be required to turn on the charging circuit?
