    Yes, you should diffidently have 12V at that point......... Smoking Gun!! Yes. You're good BUT, you have that 2'ish amp inline fuse installed? Right? Just as a per-caution, ya know :flame: Could be a lurking solder splash, or...

    Thx gm..........no worries, slice of cake!! ;) jeep! Warm up the soldering iron, you might just get to install a jumper wire!! Lets make sure tho first eh? Re-take the above measurement as prescribed just above in post #91 and we'll go from there.........As such, We might have an open, see...

    k But wait........Post #71 You had +12V once. Back up and start again.. Two wire set up again, negative meter lead to negative battery post, probe the foil again where you KNOW you measured +12V previous. A sanity check if you will...........It's (+12V) there still right? Now move JUST the...

    To a very basic setup then, just the board by itself and seen below (nothing attached to it), one 12V battery and two jumper wires needed .......... Grab the 12V battery that has nothing on either of the posts and grab the two 2' lengths of wire (optionally with alligator clips on ends and one...

    Then the red battery wire is open (or not connected properly to) somewhere from the battery + post and the soldered spade connector (battery +) seen in the pic's below, should be just a wire between your probes...... *Yes, it should, assume you'd use standard incandescent type. *Not...

    Super simple test, eliminating all else..........Use a 12V battery connected just to battery + and battery - connectors (J3, J4) shown just above and leave the white wires disconnected. Then pinch the face of the flex over the dark area's (described several posts above). This turns on the board...

    This "ground foil"? Pic A If so, No! That foil is directly connected (or suppose to) to the battery +...........It ISN"T ground, the black text is incorrect. If you had your neg probe - on that foil area while the pos probe's + is connected to the battery +, then your reading should (has to...

    Jeep, Ya might, if you haven't already, have to make sure the handle/throttle assembly is back together all the way to get it to fire up. I picked up a board like yours just out of curiosity and as such.......... I haven't drawn/scoped it out too much yet, just got it but, it looks like the...

    airguide rpm gauge

    The RPM gauge was working fine and for example, the day before you simply changed out the battery and the next day POOF, it wasn't working, dead to the world? Curious what then made you change out the rectifier? Was the battery not charging as well? Battery wires weren't reversed or anything...

    NP Jeep. I noticed an error I had above so I added an edit to #42, the power for the UA3842 is on the N.O. side of the relay's as shown below. From a trouble shooing standpoint, it is significant enough to drop a heads up. This means that the relay's have to energizer in order for pin #7 of...

    More lame attempts at paintbrush drawings/editing but, the gist is in there.... F = Forward, R = Reverse

    Perhaps this might help as well...assume brushes, commutator and armature are good to go?

    gm, not sure about this being ground foil Here's my take....... Thinking (see left image) since that foil becomes common (when relay's are on) with pin #7 (+12/Vcc of the UC3842) it is actually a switched +12V and not a ground foil.

    Ground path to pin #5-UC3842 from what I assume is the battery neg connection/terminal's (is also the N channel FET's source pins, low side switch, see simplified schematic above) ...... A9R5D3D.pdf

    HI jeep, It's what you're comfortable with, gm however said he lifted and tested all the boards passive components and such, so things should be okay on the board but............Something might be off still and it might a quick and easy for you to check and/or replace it was my thoughts. So, if...
