I don't know if this is normal under normal circumstance.
I left my TM switch on last time I put boat away (3 weeks ago), picked up boat yesterday, did not realized that I never plugged charger in till just before going to bed. This morning I opened door to garage and noticed blue light indicating TM is on. I went to put stuff in compartment nearest charger and compartment was hot. I removed container and felt NOCCO 4 bank charger and it was hot, only 1 green light for starting battery and 3 red lights for TM. Does it hurt the charger if TM is left on while charging? And is it normal for charger to feel hot?
How much draw is there to the blue light?
Thanks
