Busy at the track, got back to my coach at 11PM, need a shower bad, they don't call me klutchdust for nothing. I turned on the lights and heard that awful beep, the one that tells me the house batteries are dead. great. Most every one of my neighbors is asleep . In the morning after a ride to the pits for some jumper cables I got my genny going and a much needed shower. I looked at my battery booster in the garage the day I was leaving and thought nah.... ran two sets of cables from the engine to the house batteries.Also, I am a maintenance guy, on time and done right. Embarrassed to say I forgot my house batteries, they needed water. Check those folks. On my way to Seattle, happy trails and be safe.
