[DeTomaso] Battery question

[Asa Jay Laughton]

Brent,

I recently replaced the regulator on my Mach I for just such an issue.  
In my case, I have a good old fashioned lead-acid battery with caps on 
it.  I kept blowing the caps off, which is an indication of 
overcharging, creating too much gas in the battery and overwhelming the 
standard vent system.  My measurements were very much like yours.  At no 
time during my test run with the voltmeter, did the charge go below 16.5 
volts.

I replaced the regulator and I'm not charging right around 14.5 to 15 
where I would expect it to be and it varies by load as expected.

I new regulator was about $20 if I remember, from Napa.  The Pantera 
uses the same one if I recall.

Some more info - the Optima i am replacing was 2.5 years old and would no longer take a charge.  the new battery was a warranty exchange.  2.5 years also seems like maybe there is an issue with the charging system?
