Miswired pamco ignition sensor?????

    So I just finished installing my pamco ignition. I have no spark whatsoever. I noticed that the sensor itself seems to be wired incorrectly. The three leads soldered into the board on the sensor are red green and black. The board is also labeled this way. BUT the red and green are reversed. Can this be my problem? I know polarity doesn't matter at the coil but one lead (red) is tied into ignition and the other (green) isn't. Also I'm unsure if this can cause a problem at the advancer unit. Pete! Help!!

    Also, could someone help me verify the orientation of the advancer board? I want to double check that I didn't put the cap on backwards and wire it backwards!! I just need to know what to look for on the actual board to know what side is coil and sensor.

    ippytattoo Just another grumpy hack.

    If I remember correctly Pete posted a while back that he had a run of boards that were stenciled incorrectly but the wiring was correct. I am sure Pete will be here sooner than later and he will be able to answer all of your questions with more certainty.

    The first batch of boards had the stencil for the wire colors incorrect, with the red and green reversed. That has since been corrected. If you have one of these early boards, then the wire will appear to be reversed, but all PAMCO products are tested prior to shipment.

    The sensor side of the E-Advancer board is where the 14 pin socket for the MCU chip is. On later boards, there is a label for "sensor" and "Coil"

    You have to have power to both the coil and Pamco, Check your voltages.

    Thanks pete! Looks like I wired the advancer backwards! I took the cap off when I got it to check the board for damage as a precaution. Apparently I wasn't too mindful of the orientation of the cover! I think I'll mark the leads this time!! I'll rewire tomorrow and give a report back! Thanks again!

    Ok. I corrected the wiring issue. I have 5 volts to the sensor and 12.3 at the coil. Still no spark!:wtf: I removed the block that ties in the locating pin to test the sensor with out cranking it over. I get .4V on the green wire on the sensor when the magnet passes over but 0 going to the coil on the other side of the advancer. Do I have a bad advancer? I'll be testing the coil next. Thanks for the help Pete.

    I wasn't sure if y'all would see this unless I quoted...

    I'm purchasing a new advancer. I hope this works and not 100$ wasted.
