Craig Howe 2 #1 Posted September 1 My 416-8 has experienced the 9-pin problem...I am handy but electrical is my Achilles heel...appreciate any assistance. I have ordered a new connector kit, wonder where the white wire shown in the picture should go in my new connector (have looked at the wiring schematics but cannot seem to figure them out)...Thanks!

gwest_ca-(File Mod) 11,070 #2 Posted September 1 Welcome to Red Square 18 different models and years using the Onan engine. Have the model and serial of the tractor? Share this post Link to post Share on other sites
953 nut 55,393 #3 Posted September 1 The troublesome NINE PIN CONNECTOR was an Onan connector and is unnecessary unless you plan to swap engines on a regular basis. The diagram below shows the wiring at the nine pin and many people have eliminated the connector and soldered their wires color for color with good results. The white wire begins at a 30 Amp fuse and terminates at the voltage regulator. It handles a great deal of current (amps) and results in the meltdown you have experienced. Hope this is helpful to you. 4 Share this post Link to post Share on other sites
Craig Howe 2 #4 Posted September 1 I do all my best thinking it seems AFTER I press Send... I thought about forgetting the Model # of course after the fact, thank you for the replies...my wiring has a red, yellow, black, light blue, dark grey and three white wires, total of 8. The area that burnt out has the black wire (I know where it fits back) but that white wire I want to get in the right spot. Oddly enough, it seems to go to a spade quick connector that is not in use, shown in picture #2. This 1989 tractor was my father-in-laws retirement gift to himself in 1990, he wiped it down with an oily rag after every use, and I adopted the tradition for the past 28 years. I absolutely love it, and want to get her going again. I took it to a (very nice & qualified) local mechanic and he said its the only job that's ever stumped him...it will start but only run for 10-20 seconds and then cuts out ...have my fingers crossed that replacing the 9 pin is all it needs.

Craig Howe 2 #6 Posted September 1 Thank you for the replies, I had found the demystifying diagram for my model ...but found it mystifying...if I can ask this last question: Are there any 416-8 owners who can tell me if the connector shown in this picture/attached is left unused/unattached ? perhaps its for an option my tractor doesn't have? With your experienced help on that question, I'll try to figure out things from there. thx! Share this post Link to post Share on other sites
doc724 925 #7 Posted September 2 Hi Craig, I had to do this but it was 7-8 years ago and I have since sold off all my equipment. In addition to ordering the connector kit, get your self a professional crimping tool. Do not try to crimp the wires with one of the cheap tools that you can buy at the big box stores. You will not get a good crimp and worse yet, you may not be able to get the terminals into the housing and lock into place. I cannot remember where I bought mine but I can tell you that time it was close to $100. The other hint is do one wire at a time, first one side and then the mating side. It is REAL easy to get confused. PS: as I remember, there is also a tool to remove the terminals from the connector without destroying them. Share this post Link to post Share on other sites
wallfish 17,023 #8 Posted September 2 I've found this crimper/stripper to be the one I use the most. Cuts, strips the wires and crimps all in one tool plus you don't need to get the terminals into the middle of the tool to crimp it like some. Heavy duty and will last. 7 + years now and it mostly gets used at work quite a bit https://www.homedepot.com/p/Klein-Tools-Forged-Steel-Wire-Crimper-Cutter-Stripper-2005NSEN/309328460 Share this post Link to post Share on other sites
Craig Howe 2 #9 Posted September 2 Thanks doc, and Thanks wallfish ... I have putzed around with those same pins in my day job (repairing electrical connections for spraying equipment) and although I got them and soldered just to make sure, it took wayyyyyyy too long. So I did order the crimping tool at the same time as the connector & pin kit. I am going to follow your 'one pin at a time' advice. Appreciate the feedback, by chance would you have a sense of what that unused connector may be for that I show in the attachment? I have seen it in You Tube videos sitting in the same spot ...but it tickles my brain to wonder what it might be. Appreciate your kind advice, really do. Thanks again.
