Ok, I have what is probably a stupid question. I have the True UTV-SBI-15CM UTV Dual Battery Connect and a Odyssey PC925 as my second battery. The Blue light comes on and goes off so I assume that it is working correctly. I had the negative from the second battery attached to the negative of the first battery and then switched it to be grounded directly to the frame but what is happening is my RZR will not start and the Odyssey PC925 battery will be totally dead if I leave it stored for the week. When the batteries are fully charged and sitting on the bench they hold their charge but if I leave everything hooked up there appears to be some sort of drain. Does anyone else have the same issue. I make no changes to the stock wiring and if I remove the isolator the stock battery will retain it’s charge when stored.
