Yes, I measured the voltages and they are fine.Mine for sure doesn't look like this.... Did you measure the voltage?
Ok,I used contact spray on electric fuses and tripmaster works now. Everything is fine, previous owner changed rectifier and made it like that I suppose... voltage is ok, nothing to worry about it seems...Then maybe the tripmaster fail was not connected to the regulator... I don't think this regulator is even from a XRV because the original one doesn't have a plug like this one. Maybe a previous owner soldered the cables to the plug. It is possible that that's even be a good fix if done correctly.
My tripmaster failed fully when it did. I don't know what the 8888 means, but maybe someone here has had a similar experience?
