Britton Baker 4 #1 Posted March 28, 2017 (edited) I have a 1963 753 with the k161 kholer and my wiring has burnt twice. The first time had the voltage regulator cover off and I saw the contacts stick together then all wiring was melted. I have since then rewired it and the same thing happened again. I have looked in my manuals at the wiring diagram and I have done it correctly. My question is could I put in like an inline fuse or does anyone know the solution to this or has anyone had this problem.

Britton Baker 4 #2 Posted March 28, 2017 This middle wire burns first and the wires from the amp meter. Also this one on the back. I think this is where it goes. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,444 #3 Posted March 28, 2017 Will let the more experienced respond to your problem. Here is a link to a Kohler manual that covers this system so you have it available. This is the one you want to download. Kohler 4-72 SM Section 07.1-7.6 Starter - generator HR.pdf Garry Share this post Link to post Share on other sites
953 nut 51,029 #4 Posted March 28, 2017 Your center terminal on the voltage regulator should go to the battery (if you have an amp meter it will go to it and then to the battery). If that is smoking you have a short to ground in the regulator or some other place. Take a look at this guide and diagrams. The diagrams are not but have some good info.

squonk 38,572 #5 Posted March 29, 2017 My guess is the ammeter. I have seen a few bad ones and if it's original, it's time Share this post Link to post Share on other sites
Britton Baker 4 #6 Posted March 29, 2017 The amp meter is original and also my wiring diagram for the 753 looks nothing like that. Wonder what it could be I have seen a few different diagrams. I guess thats just the joys of the tractors. Tanks for the help but im still dumbfounded Share this post Link to post Share on other sites
pfrederi 17,043 #7 Posted March 29, 2017 (edited) Terminals on the Regulator are corroded looking, Clean them up they are stamped B (battery to teh left as you look at it G in the center F to the right goes to F terminal on Genny Is there a terminal in the bottom of the regulator? Something doesn't look right in the pictures? i doubt that is the original regulator you said the contacts stay shut in the regulator??/ Can you work a points file between them to free them and clean them??

pfrederi 17,043 #8 Posted March 29, 2017 (edited) If you have a 4 wire regulator (one on the bottom 3 out front the wiring changes a bit) The under wire goes to the A terminal on the genny along with a heavy black wire from the starter switch The front three are then L (Load) BAT (battery) F Field L will go to the igniton switch Bat will go to Pos terminal on battery Normally would go through the ammeter but since it may be a problem leave it out of the circuit for row F goes to Field on Genny Edited March 29, 2017 by pfrederi Share this post Link to post Share on other sites
Britton Baker 4 #9 Posted March 29, 2017 I think the regulator is original once I rewire it again I will file down the contacts. Should I wire in a fuse tho to be safe. Im a newby to electrical but I can fix the mechanical issues Share this post Link to post Share on other sites
pfrederi 17,043 #10 Posted March 29, 2017 Does it have a terminal on the bottom of the regulator? An original would have a black case not white. I am working on a longer post to help you run this down. Share this post Link to post Share on other sites
Britton Baker 4 #11 Posted March 29, 2017 Yes there is a terminal on the bottom. Sorry it has beem painted white by previous owner. I will fix everything eventualy Share this post Link to post Share on other sites
pfrederi 17,043 #12 Posted March 29, 2017 (edited) That is key. the wiring diagrams are inaccurate in that area. The bottom terminal should be connected to the A terminal on the Genny (along with the heavy wire from the starter switch) That wire doesn't appear in the wiring diagrams (it is part of the S/G itself not a WH part.) The left terminal on the front of the regulator is the load and goes to the ignition switch The center one is battery. Until you are sure you ammeter is good i would wire it directly to the battery positive. Right is Field goes to F terminal. You do not need a fuse If you get it running take a voltage reading.

Britton Baker 4 #13 Posted March 29, 2017 Thank you so much I still have two more questions. One how could i test the volt meter and two could this happen agin if it is wired correctly with a working amp meter. Share this post Link to post Share on other sites
pfrederi 17,043 #14 Posted March 29, 2017 I meant hat you should use an independent multi meter to get a voltage reading while it was running ..should be 13.6 to 14.6 v If it works OK bypassing the ammeter then a new ammeter will solve it. However if the contacts in the regulator are badly burned or stuck it may happen again. 1 Share this post Link to post Share on other sites
Britton Baker 4 #15 Posted March 29, 2017 OK thank you that 7hp kohler runs great just electrical isssues wil tell you if I have any more issues 1 Share this post Link to post Share on other sites
