Should have a device to get that 88-108 Start Cap OUT of the circuit once the compressor's spooled up close to operating speed. Coleman offers a Start Relay or a Positive Temperature Coefficient Resistor (PTCR), depending on Model, sometimes offers a choice. Chris Bryant says the Coleman Start Relay works better than a SUPCO SPP6E (for Electronic) start kit (cap + electronics in one housing. And the SPP6E is better than the Coleman Cap + PTCR setup or the SUPCO SPP6 (no "E") that's also Cap + PTCR but all in one housing. Dometic sells a start kit that Chris says is THE best, but I know nothing about it or if it would interface with Coleman.
I'd be interested in the Amps Draw specs for Mach 8 and the ordinary 13500. Could you post the complete Mach 8 model number? I'd love to look at the parts list and see those two motors!
