Boat Repair/trim draining battery

Expert: Jeff Grigg - 1/18/2008


Question
my trim motor is draining my battery on the spot, system goes up and down if i keep a charger on the battery.

Answer
Joel, I'm not sure what you mean. Are you saying the trim goes up and down by itself? Is that how it is draining the battery?
If so replace the relays.
If the trim system is consuming excessive amperage, your trim motor may be at fault.
Please post back if necessary with the year and model of your motor and exactly what it is doing.
