Kettlewell, are the regulators that you posted the internal type?
Yes. Those are internal regulators for 10SI and 12SI Delco alternators. I have switched around and tried various ones.
Someone else was asking about charging
your starting battery at the same voltage as your deep-cycle house batteries. What I do is have all the alternator
output go directly to the house bank of deep-cycle batteries with a Trik-L-Start that feeds charge to my starting batteries once the house batteries are getting a decent charge. The Trik-L-Start drops the voltage by 0.2 volts, which seems to work out well for the starting battery. I also feed all the solar
panel power direct to the house batteries and the Trik-L-Start keeps the starter battery ready to go no matter what. Remember, there is no reason your starting battery should get a deep discharge--if you are discharging it a lot, something else is wrong with your engine
. If it doesn't start right up, you should fix that problem first. Therefore, your starter battery never needs much of a charge.
