Wow! These responses are great,thanks for all the help so far. So here is an update.
Bulbs for brake lights are the same for tail and bulbs are fine. Rear blinkers work fine as well. Checked the only fuse panel I could find and there was no fuse I could find. So will test ground at bulb?
I checked and yes there are 2 tanks. Front tank and rear tank. The rear tank is main and front is alt. When idle or off flipping the switch does nothing that I can see change or hear.
Not aure what grey tank is made of but will post a pic.
