mariuszaerox 12 #1 Posted August 31, 2019 hello I did engine overhaul and now I have a problem with a lack of spark. Someone was undressing in front of me and now I can't decipher the electrics. Could I have an electrical diagram? Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,488 #2 Posted August 31, 2019 Welcome to the forum. Is this a C-161 or a C-161 Twin? Big difference in the wiring because the C-161 Kohler has battery ignition and the C-161 Twin Briggs and Stratton has magneto ignition. Garry Share this post Link to post Share on other sites
mariuszaerox 12 #3 Posted August 31, 2019 (edited) Hello, C161 Twin, Briggs 16 hp Which cable should be plugged in? Should all pins be occupied? Edited August 31, 2019 by mariuszaerox Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,488 #4 Posted August 31, 2019 In case you were not aware the B&S ignition is self-powered. The single ignition wire coming from the engine is simply grounded to shut the ignition off. Not grounded the engine should run. Do NOT allow any battery power into the ignition wire as that will burn up the ignition coil. Hope this bulletin shows how to connect the isolation relay. Let us know if you need more.

gwest_ca-(File Mod) 10,488 #5 Posted August 31, 2019 I would leave the ignition wire to the engine completely disconnected until you are sure the ignition switch grounds the proper relay terminal with the ignition key OFF. With key ON the correct terminal is not grounded. This bulletin may help also Garry 1 Share this post Link to post Share on other sites
mariuszaerox 12 #6 Posted August 31, 2019 I connected the cables as I wrote ALTER ATE 5-TERMI AL 106833 RELAY Further when connecting the + cable to the battery, sparks fly ... Share this post Link to post Share on other sites
mariuszaerox 12 #7 Posted August 31, 2019 Ehh, I still don't understand where this yellow cable should be plugged in, I am weak in such technical drawings. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,488 #8 Posted August 31, 2019 Looking at the wiring diagram the yellow is the AC power from the engine stator to the lights only. The lights will work on AC or DC power. The other charge lead (orange) has a diode in it so the output is rectified producing DC current to charge the battery. For a quick look click on the picture and again on the next page.

gwest_ca-(File Mod) 10,488 #9 Posted August 31, 2019 The black or green wire from the engine ignition is not in your relay pictures - Terminal 1. Leave it off for now. Terminals 2 and 5 are for ground wires. Terminal 4 should have a purple or violet wire from the pto switch. With the pto off turn the ignition key to ON or Run and you should feel the relay click when key is turned on and off. When the happens instal the green or black ignition wire to terminal 1. Everything should now work. Garry Share this post Link to post Share on other sites
mariuszaerox 12 #10 Posted September 1, 2019 Hmm, the transmitter just clicks, I connected the cables as in the diagram and there is still no spark ehh Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,488 #11 Posted September 1, 2019 If you remove the magneto wire from the #1 terminal on the relay and isolate it so it does not touch the chassis ground the ignition should work allowing the engine to run. If it does run with the ignition wire isolated the problem is in the relay or associated wiring back to the ignition switch. If it does not run with the ignition wire isolated the problem is with the engine wiring or magneto or spark plug. Remember the B&S ignition is self-powered and the wire to the relay is only used to shut the ignition off by grounding the ignition wire. Garry Share this post Link to post Share on other sites
mariuszaerox 12 #12 Posted July 21, 2020 Hello, what is the gap between the contacts under the carburettor in mm? Share this post Link to post Share on other sites

Presuming you are asking about the ignition points gap it would be 0.020" which should convert to about 0.5mm with the points open to their maximum opening.

mariuszaerox 12 #14 Posted July 23, 2020 hmm, what kind of oil should be for the transmission? wheel horse c161 twin automatic Share this post Link to post Share on other sites
pfrederi 17,129 #15 Posted July 23, 2020 what color is the fluid in there now? Red is Automatic Transmission fluid (DEXRON or DEX/MERC)) Tan would be motor oil 10w30 or 10w40. Either one is fine just stick with what is in there and DO NOT mix. them 1 Share this post Link to post Share on other sites
mariuszaerox 12 #16 Posted July 23, 2020 oil is also leaking somewhere near the right rear wheel, could I ask for the seal numbers or sizes there? Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,488 #17 Posted July 23, 2020 1978 C-161 Twin model 81-16BS01 1979 C-161 Twin models 91-16BS01 and 91-16BS02 6449 axle seal is the same for all if that is the source of the leak. SKF 11124 is a replacement. Garry 1 Share this post Link to post Share on other sites

gwest_ca-(File Mod) 10,488 #25 Posted July 26, 2020 The green wire in these drawings is the magneto ignition wire. If it is disconnected the engine should run but not shut off with the key switch. If you can disconnect the green wire and the engine runs the problem is with the safety switches. If it will not run the problem is with the engine magneto ignition. Click on the picture to see more. One picture shows how the ignition is controlled. You can also download the pictures in pdf format. Garry 1 Share this post Link to post Share on other sites
