Yes, the Solder splash is the only likely expalantion if it happened once , but to have it happen twice, and get a solder splash to create a short across the pads where the SMD was...umm..unless a splash some where else and it is still there.
But that can't be right either. I have measured each of the SMD's and they are correct, and the series resistance of them is correct too, if there was sshort somewhere, those figures woudl not be correct.
As for the correct power resistors....
no, I never changed them for 100volts, but I have only used it for short distances at 100 volts and it has always worked so far.
AM down in workshop now, and fired it up with 75 volts.
Good 5 volt at throttle output,
Cruies control warning light comes on when power is applied to the board, and Cruise locks on when the throttle is opend and Cruise is activated.
Cruise knocks out too, when the e-brake line is shorted to earth. so all that side is working. Just motor does not turn
So this points to something else gone..but what woudl that be where do I look next?
