Title: Inline Resister in the Red T-2 throttle wire
Post by: Kirk on May 26, 2012, 04:46:51 PM
Anybody else have an inline resister in the T-2 throttle wire? If so what is its function. It isn't on any of the wiring diagrams from GM that I've seen. Its on a Pro 901 48V 1000W kit. I think the controller part number is BAC-0282P

That looks like a capacitor to me.  By the size and shape of it, it is probably what is called a bypass cap, used to reduce hi frequency noise from a  signal.

Thanks I'll see if I can find a mate to it at Mouser or Allied and see if I can get the specs on it. The markings on it are too obscured to figure out what they are, even under a magnifying glass. Probably don't need it but it would be nice to know.

I wonder if it's a current protection device to protect the hall sensor in the throttle. ???

A similar item was fitted to the external controller wiring in this post:

After seeing how the device is wired in Alan's photo, I'm not so sure it really is a bypass cap.   The layout just doesn't look right.  The wiring is pretty large, both the same color, and at a distance from the connector.  That doesn't match a typical wiring of a bypass cap.  But having said that, the shape, color, lead layout, and marking layout are typical of a small value capacitor used for bypassing.   

Can you read any of the markings?

TTFN,
