Hi,
I have a Coleman UT400 that is a couple years old (2021), that won't seem to hold a charge. We have replaced the battery several times, and the unit will startup and run for a period of time, then die out. When I attempt to restart, it acts as if the battery is weak. Install a new battery, and it repeats the cycle.
Do the magnetos go bad on these things? If so, how hard are they to get to and change?
Thanks!
Kyle
