    So I'm tracking down a short or issue with my #6 connector on my AGBGoaWT. I'm trying to test for continuity at this point.

    A few questions:

    #1 Is this OK to check for continuity or do I need to cut/cut into the wire?

    I'm using a clip at the coil where the wire is connected, the other end clipped to the dmm probe, and then testing with the other probe at the pin # associated with this wire.

    #2 If this is OK, and I get continuity through several pin positions, what does that tell me? Ground issue; touching wires; Aliens have landed???

    This is connector H6-3 if it helps.

    Fuse F17 blows after a few seconds of turning the machine on. I removed all of the connectors and replaced one at a time, leaving them in as I went. When I got to connector H6, BAM!. I removed that connector and continued to replace all other connectors. So I'm guessing that connector is the issue.

    I know H6-3 goes to F15, I just started with that particular coil because it was easy to get to. When I tested it showed continuity, but it also was showing for other pin #s as well, hence question #1. I was worried I wasn't testing correctly and getting false readings.

    Thanks for all your help, I'm completely new at almost all of this stuff.

    Yes, I removed all of the connectors to see if it was a board issue or connector issue. And then to identify which connector/wire to investigate.

    I do have some starting points to check from the TEST MODE so I guess I'll get to testing and comparing some of those values.

    Also, here is the matrix that came with my manual, it is a little different than the web version, some pin numbers are different as well.

    When I tested both h6-3 and h6-2 the resistance value for pins #10 and #11 shot up to around 80. I don't know if this means anything but thought I'd post it in case it does.

    OK, I'm off to run some tests, again, thank you!

    Yeah, that's along what I was thinking. They were all reading either close to 0, 1, or 80.

    I just thought that since those particular pin #s were showing very different values it might be indicative of something.

    Guess not.

    I'm trying to pry off my apron now so I can check the "Feedback". That was one of the test mode's issues.

    Thanks!

    I think I should start a new thread specifying my coil issues as I gain more information.

    Thank you both for your help.

    #11 6 years ago

    I hadn't thought of that. Yes, all other connectors seem OK.
