Last weekend, my cranking battery died on me, or so I thought.
Change it out the other day, installed a new AGM. Got on the water yesterday, and noticed that my voltage was pulling down to around 11 volts while running if I got on the trim. Is this normal, or do I have an alternator or voltage regulator problem?

What is your battery voltage (tested at the battery) with the engine idling?
Are the battery connections CLEAN- ENGINE CABLE INSTALLED FIRST, remaining lugs "largest to smallest", and a STAINLESS LOCKNUT finishing off the connection? (Don't use wing-nuts)

Voltage at the battery is the only thing I don't have.
It is installed correctly.

Check voltage at the battery with a digital voltmeter.
You should be seeing 13.1-13.8 VDC at the battery after engine has been running 5-10 minutes.
Be glad to assist further... once you've checked this.

I was recently plagued by electrical issues with TM and Cranking batteries. Cleaned up my connections re tightened everything down and all seems good now.
