I completed my first WBB conversion to Proto Sound 3. The engine (a GP-9) was running well then started acting weird. The engine developed a shudder as it ran down the track.
After taking the shell off I found what the culprit was. I had carefully routed the wires up onto the top of the inside of the engine shell using dabs of clear caulk to hold the wires in place. What I discovered was; there must be very little clearance between the top of the flywheel and the top of the inside of the engine shell because the flywheel had burned through the insulation of the front marker lights and number plate lights; shorting them out.
So now I'm in the processing of removing all the wiring for the lights from inside the engine shell (and held in place with dabs of caulk) and rerouting them around the two motors.
As you can guess, removing the wiring from the dabs of caulk is challenging. The caulk really holds the wire well!
I'm sure you're thinking "why in the world would he use caulk as an adhesive to hold the wires?!" Well....I was looking for an adhesive that was 1) safe to use with the engine's plastic shell, 2) safe with the wire's insulation, 3) would hold the wire well without coming loose over time and 4) would be easy to remove the wires from (like in my current situation). Caulk seemed like a good solution...at the time.
This finally brings me to my question. Do any of you have any ideas or suggestions about an adhesive or maybe a better approach to hold the wiring in place inside the engine's shell? I'm at a loss right now.
