funny thing is that even after starting it with it not being started for 30 minutes, the gauges do the full sweep thingy and the odometer resets to zero. does that happen to anyone else?
After researching various batteries for winch duty in my Jeep, despite the claims by Hawker, I decided they wouldn't work. They may start okay, but they have poor reserve capacity. IOTW they will die quickly if they have very much load placed on them without charging. The above quote tells you that the Hawker is going below the minimum voltage necessary for the odo memory. I have experimented with this and it seems like the trip odometer is the first to go on low voltage. The ECM and radio presets will usually stay until you drop below 8 volts or so. IMHO the Hawker is an decent idea that has not been fully developed yet.
