I want to reset the onboard computer to default settings. I believe this can be done by disconneting battery for 30 minutes. Which terminal should I disconnect (positive +, or negative -, or both) ? Thanks.
Either disconnect the battery or pull fuses #4 and #11 for a couple of minutes. Then hook up the battery or replace the fuses. This takes it back to factory settings. Works on my tour.
