Melatv 792 Posted August 26, 2021 Hi: The Main fuse 1 only feeds power to the fan motor and the shift motor. Share this post Link to post Share on other sites
Tobor1 39 Posted August 26, 2021 That would narrow things down quite a bit. as you suggested other night the shift motor is still unplugged.I need to go pick up more fuses now but this morning I will start Tracing wires looking for bare contact spots with frame 1 1 Share this post Link to post Share on other sites
Melatv 792 Posted August 26, 2021 (edited) Hi: Do you have one of those 12 volt light testers? If so use it instead of the fuse, you may need jumper wire to connect the test light in where the fuse goes. --- how it will work the test light will stay on until you clear the fault that was blowing the fuse -- it will go off when you clear the fault. unplug 5 pin connector on the PCM to start your testing.

Tobor1 39 Posted August 26, 2021 I sure can make one. Share this post Link to post Share on other sites

I made the mistake of buying cheap chyna fuses on ebay/ amazon and they actually melted into the fuse block. Learned my lesson on that one. Good fuses are pricey for what they are, but when the cheap ones melted and made a mess of my fuse block, lesson learned. 1 1 Share this post Link to post Share on other sites
Melatv 792 Posted August 26, 2021 Hi: You have the test light plugged in where the main 1 fuse goes? you unplugged the 5 pin connect and the test light went out? 1 Share this post Link to post Share on other sites

Melatv 792 Posted August 26, 2021 So if the test light when out -- now the problem is either PCM or the cable going to the shift motor --- lets check the cable --- the shift motor is unplugged -- put your meter on the lowest Ohms scale -- test the 5 pin connector -- place one meter lead on the red wire of the 5 pin connector and then with the other meter lead check the other 4 wire in the 5 pin connector -- should have no readings. 2 Share this post Link to post Share on other sites
Tobor1 39 Posted August 26, 2021 PCM. We are talking about. CDI box ? My god I’m embarrassed. Share this post Link to post Share on other sites
Tobor1 39 Posted August 26, 2021 I might add. CDI box is 3,weeks old. Shift motor is 3 weeks old. I may have just inherited somebody else’s problems Share this post Link to post Share on other sites

Tobor1 39 Posted August 26, 2021 (edited) one lead on red other 4 oL each shift motor still unplugged Edited August 26, 2021 by Tobor1 Share this post Link to post Share on other sites
Melatv 792 Posted August 26, 2021 (edited) Okay -- key off -- now put your meter on the low ohms scale again -- place one meter lead on the neg. of the battery and with the other meter lead test each of those 5 wires in the 5 pin connector.

Melatv 792 Posted August 26, 2021 Okay -- those tests are good only one green should have a reading. Now check the PCM 5 pin male side for bent pins and corrosion. 1 Share this post Link to post Share on other sites
Tobor1 39 Posted August 26, 2021 I see no corrosion or bends. 1 Share this post Link to post Share on other sites
Melatv 792 Posted August 27, 2021 Good -- put your test light back in where the 30 amp main 1 goes. -- put key on does the test light up? -- if not turn key off and replace the 5 pin connector into the PCM then turn key on does test light come on? -- if so pull out the fan fuse -- does the test light stay on?
