View Full Version : Motor capacitor question

I recently switched from 19T to Stock....While At the track I was getting
a glitch.....I run Green Machine 3's (until I buy some new monsters)...I finally
installed a motor capacitor and the glitch went away......However someone told
me that it will rob the motor of a little amperage............I find this hard to believe.......Anyone here anything along these lines......?.......The reason I am asking is because the lap times dropped a tad in my last run....I cant believe running motor capcators can hurt a motor...Even the newer stocks that have them already installed.......But im new to the stock thing...

Bud 3738. I Still race green machine's and I install three small novak capacitor's on mine.and i do not have any speed difference. I will however remove those factory capacitors first. I always thought a spring loaded connection wasn't worth awhole lot anyhow. And I tested mine using Lap counter.No difference other than Glitch was gone.

Remove the factory caps first,then apply the wire caps.the factory tend to short out,which is probably causing the glitch.

I will remove the caps....where would they be on the G3...also the newer stock motors today...would they be is the same place..?.....

For GM3's (and all early "built-in capacitor" EPIC motors), the tiny capacitors are in the same set of locations.... One is in the spring loaded "tunnel" from + to - at the end of the endbell, just above the bushing. The other two are at each end of the roughly triangular tin piece at one of the endbell screw locations -- on each end, there is a tiny z-bend and the capacitor is loosly held between the tips of the tin piece and the underside of the hood heatsink....

The flaw in this series of motors is that all capacitor connections are spring loaded, and are thus subject to vibration, fatigue, phsical shocks, infiltration of dirt, oil, etc... NOT a good thing for electrical connectivity...

The newer EPIC's use that small circuit board on the end of the endbell...
