Got a jump start at the FastTrac/Denver Airport parking last week; and lost functionality of the fuel level gauge the over head gauge. Both are back on but erratic. I didn't think much about it at the time (during a downpour) but the guy hooked his truck plus a jumper battery all to one my passenger battery. Isn' that 24volts to a lot of 12 volt circuits? Still took a while to build up enough oomph to turn over. Could all that juice over 5 or 10 minutes have fried the gauges?
