Stern SAM board switch drive transistor failure (SOLVED)

<< < (2/2)

lilshawn:
i used some thicker "splicing tape" it's like electical tape, but about 5x wider and about 3x thicker.

ya i painted some clear nailpolish over the rubbed through portion of the coil wire insulation... i also wrapped splicing tape around once on the coil and placed a layer on the plate under the coil for good measure. i also ground down the tips of the screws for both the mounting plate and the flat rail. i also used a plastic washer on the flatrail screw for extra insurance.

this scenario is unlikely to happen again.

BobA:
Nice troubleshooting.  :applaud: :applaud:
