The fact that your second battery boiled over suggests that your alternator
was overcharging. You said you had that fixed but I wonder. Your charging
system may need a closer look. Your alternator may check out but is your
wiring
OK? A friend of mine went through half a dozen alternators before he found a
bad connection that was causing all the problems. Go back to Canadian Tire
and buy a $10 DVM and get some voltage readings. If your voltage is over 15V
or
if it is under 13V you still have a problem.
