This was an interesting problem. Originally I thought this was probably the shift lock relay. When I measured the resistance to ground on the negative side of the coil I saw ~35 OHMs. This sent me chasing a loose ground connection, but after further fault finding, it was actually the Park Position Detect Switch. The switch was not closing completely. After some coaxing and bending I got the thing to make, tested it and wala! It works. I'm back to normal operations. <img src="/forums/images/graemlins/kewl.gif" alt="" />

My suspicions about the key switch and shift lever were true. They are interlocked. When the key switch is in the ACC position you can press the button on the shift lever and move the lever where ever you want.

HereÆs a schematic of the circuit with some coarse sketches of the component locations.



The Electrical Troubleshooting Manual (from Helms Inc.) is an extremely helpful guide. Not only does it show the schematics for all the Rodeo/Amigo circuits it also shows pictures of where all the components are located as well as all the connectors plus the connector pin outs and wire colors. The shop manuals have been indispensable while DIM (doing it myself).
