Funky dash warning lights
After three days of boondocking using only coach battery power (two batteries, new automatic isolator) and only depleting their charge to 2/3, when I started the coach, easily, three warning lights remained on-- ABS, traction control and some anti-skid function. As nearly as I could tell, these lights come on if the chassis battery is run down, but after i had run the rig for about 15min, my voltmeter showed 15.6v with the ignition off.
150mi ride home, lights stayed on, cruise control was inactive, engine performance seemed normal (pulling a trailer over hilly roads).
I have a 750mi trip this weekend, so I want to figger this out SOON.
Thanks for your help.
