ELECTROSPORT ESR510 REGULATOR WIRING

[jsey]

Hi All
I’m hoping that someone here has installed the ELECTROSPORT ESR510 voltage regulator on an 1981 900 SS. I’ve wired it according to the diagram provided. Green wire to the neg battery post, Red fused wire to the plus side of the battery, two yellow wires to the two stator output wires, white wire to the white coming out of the harness down by the fuse box that goes to the generator light on the dash. Black wire not used.
The problem I’m having is when the ignition key is turned on, the regulator get very hot and a small amount of smoke was produced I think from inside the regulator. I wasn’t quite sure where it was coming from. None of the wires seemed hot or melted. I may have fried the regulator on the inside or it may be defective. I am told by Electrosport that you can’t test the diodes on a MOSFET regulator the same as you would on a shunt type so I’m not sure where that leaves me. When I turn the ignition key on the red generator light does come on and only does so if the pink and black tracer wire coming out of the harness in and around the fuse box is grounded. What’s seems odd to me relative to the green wire from the regulator that attaches to the negative side of the battery is that there is no continuity between it and the bikes ground. Any and all help much appreciated.
