    Shakes hands with danger

    Not knowing much of anything about packaged aftermarket EFI conversion kits, this is a guess, but a warning of "RPM stall" seems to indicate that the unit is not seeing any indication that the engine is turning over. One would assume the ECU is not seeing the signal from whatever sensor the system uses to report engine RPM.

    Did you know? Willys is just Willis spelled differently, but pronounced the same. Neither Willy nor his apostrophe are involved.

      Good call. I started at the distributor. disconnected the harness pulled the cap bumped motor until the rotor was pointing at #1.... Reinstalled cap pulled the #1 plug wire plugged harness back in put ignition key in the on position grabbed spare plug put it in the plug wire and rotated back and fourth the dist to see if plug would spark against metal. Nothing.....



      Next I started looking for spark at the coil and found that the coil is not receiving a power signal from the ignition box harness for the coil.



      The Ignition box is powered directly from the positive and negative on the battery. An extra ignition box came with it and it does the same thing. no coil power coming out.



      Seems weird to me. There is a light on the box that glows orange. That probably has something to do with my problem. I assume.

        Assume no more!


        There's a little rudimentary troubleshooting guide in that document as well as a tech hotline to call. There aren't too many wires to trace if it comes to that.

          I have it wired like the pic. I need to grab my mulitmeter and confirm my keyed wire is correct. It has to have something to do with that.


          I need to double check the ground from engine to frame also.

            Super cool update:



            After taking pics and asking questions on a sniper specific page my no spark problem is solved. It was too late to try to actually fire it up tonight. I really wanted to.



            This is a used system that had a wire cut under the protective wire sheath. (I think it was from the other guy trying different components) and another one spliced on that went nowhere. I reconnected the wire and got the RPM signal back.


            We are in for a few days of rain here so I will fire it up after this storm system passes and see if will move!



            Next I will get all of the wires weather proof and routed in the permanent locations, then start working on the dash gauges.

                I see the radio section of the dash has been cut out just like mine. I suppose it makes for easy installation of a newer single DIN radio head. I removed a stock AM/FM/CB radio several years ago from a Wag I found in the Pick and Pull. It was a nightmare getting it removed. The glove box had to come out first. Even then, the vent ducting behind the radio wouldn't provide enough clearance to remove the radio. After a mighty fight, I won. But now, I cannot install it into my wag because its dash has been cut up by the previous owner. Here's a link to my AM/FM/CB Radio

                  It had a single DIN radio that had seen better days. I found a clock block off plate and might put the switch panel back in where the ash tray is suppose to go. It was missing the glove box all together. Easy access. I removed an AM/FM stock radio out of one at a wrecking yard also.... Huge PITA with glove box in.



                  What are you going to do with the

                  cb?

                    I'm getting the gauges ready to go back in.


                    I'm also filling in the rust pits with spot filler on my glove box door.



                    A friend just bought this cool old bike. I figure there are a few bike fans on the forum.

                      I like the gauges, is it Dakota digital ?

                      the engine turned panels are cool.

                      looks like you got glove box lid ready to prime/paint

                      really cool BMW motorcycle too.

                        Driftwood, have you looked into the Din repair kits?
                        DIN stands for "Deutsche Industrie Normen" which the Germans starting using to standardize radios in Audis, BMWs, Mercedes, and VWs in the mid 80’s.  It has since become the industry standard. These kits enable you to mount a RetroSound® Motor 1, Motor 2 or Motor 4 radio into vehicles that have been either altered to a
                        1974 Cherokee S. It's driving but needs more work. As usual!

                            That is a pretty cool option. Would it work with a factory radio or one of their retro radios only?




                            I have a really cool update!


                            The Beast runs again! It's almost weird because it is so quiet and very smooth. It has great cold oil pressure and really good vacuum.


                            Now that it runs It's time to button the wiring up and get the gauges installed.



                            Here are a couple pics from tonight.





                            Just condensation. no smoke!









                            I'm super happy. I took a video, I'll probably post it on FB on the jeep pages there.

                                It seems like it's going to be a few days of dealing with wiring.


                                Today I installed the powermaster 1 wire alternator. (mostly to support the sniper).







                                It's time to figure out the sniper and Dakota gauges. Does anyone have this set up? If so any pointers?



                                I have the 10 pin harness on the sniper, so it might be easy. I'm just not sure what to do about all of the existing wires behind the dash.


                                Because I reinstalled the front winch bumper I need to get the winch operating. The old solenoids are pretty crusty.






                                I bought a solenoid kit similar to the Allbright, I hope it works!



                                I'll be road testing it soon. Then it will be time to do the floors.
