Thank you for the feedback. I had installed a new optima battery and it works fine if I hook it up to a bench charger occasionally, but it was not being properly charged in the vehicle. The previous owner had hard wired (through a new relay) the cooling fans to run all of the time because he had read that D's tended to overheat. I need to correct that issue, but have trouble with wiring due to a slight color blindness. I'll call a friend. The extra power draw can't be helping. I see that you have a 140 - 150 AMP unit and I will investigate it. Thanks again. --- In dmcnews@xxxxxxxxxxxxxxx, "John Hervey" <john@...> wrote: > > Lee, The Motorola and the Ducy struggle under the best conditions to keep > the battery charged.
