How is the reg bad ? over voltage ?
Our paso's are know for electrical issues as they age , one thing worth mentioning is .......... some new reg/rect's ( and I think the shindingaringganggoo is one ) have a wire that is supposed to be connected to the switched side of the ignition switch , this is the reg/rect's voltage sensor wire , problem is that often by the time the volts have made it thru to the switch some may have been lost ( skinny wires and poor connectors ) and this can cause over charging because the reg/rect only sees the voltage at the switched side of the ignition switch , if it supposed to be 14.5 v and we loose say 2v the sensor only sees 12.5v and ups the charge rate to compensate . The upshot of this is that while the sensor is now seeing 14.5v the battery (reg/rect output goes straight to the battery ) is actually getting 16.5v , So either you need to ensure there is no voltage drop to the switched side of the ignition switch , or fit that sensor wire straight to the batt +. If your having battery issues like short life or it uses a lot of water this could be the problem.
