It may be better in this case to fit an Ammeter instead of a Voltmeter. 
The current is the decisive factor for heat build up and thus failure. 
Normally one would fit a Voltmeter with an alternator, but then the 
usual alternators do not show these alarming signs of heat build up of 
these generator look-a-like alternators.
