Yep...sounds like a little to much juice. Sometimes it works best to power accessories directly off of the battery. You will likely has less voltage spikes and power variences.Try adding an accessory terminal block powered by the battery. The adding even more accessories will become much easier in the future. Most solid state accessories don't like voltage spikes, it causes smoke to leak out of 'em. The battery will asorb those so you will have much happier and longer living accessories..... Randy
