My car has blown two rap modules and after further checking, it appears circiut 75 (connector B) has a short to ground and I want to know if it goes anywhere other than the fuse panel. Is there anyplace in the wiring that would cause a short like a sharp piece of metal, etc? It would be really nice to know exactly where that wire runs from the rap module to the fuse panel.

Circuit 75 on the dark blue wire goes from the I/P fuse panel through the large 48 pin connector (c200) located by the LH kick panel and then onto the RAP.

However, if that circuit had a short to ground, it would blow the radio fuse #17 (15amp) and it would blow the power accy fuse #7 (15amp). These 2 fuses would blow before any damage could be done to the 2 internal relays in the RAP. It would appear that a short on that line would not damage the RAP.

You didn't mention the fuses, how did you conclude that line was shorted to ground?

 

fuses never blew. I used an ohm meter to check resistance to ground, and it was 0.1 ohms. This is with the rap module disconnected. I woule not think the fuses would blow if the short was before them. The rap module seemed to act as a fuse when it blew.

 

Would someone check the resistance to ground of the blue wire to connector b with the rap module unplugged so I can have a reference? TIA.
