cabin4me 1 #1 Posted September 20, 2017 Hey guys I need some help with my 79 wheel horse c-111. I upgraded the engine to the 16hp vanguard. I am wiring everything up now and ran into a little silver metal box with the letters b s h on it. The H goes to ground and one other wire goes to the shut off. I need to know what this little box is. Thanks for any help. Share this post Link to post Share on other sites

gwest_ca-(File Mod) 10,499 #4 Posted September 21, 2017 Lights are a little brighter today. The b s h sounded familiar but couldn't connect the dots. That will be a kill relay. The B&S engines use a magneto ignition so no battery power is needed or wanted in the ignition wire. Wheel Horse at the time used a battery style of ignition switch plus a kill relay to control the ignition. There were two different versions of the relay used.

cabin4me 1 #7 Posted September 30, 2017 Not real sure what it is. I am starting to think it's something to do with the safety system. All of the safety sensors wiring goes through it. I have the new engine running and charging, so I think I am going to leave well enough alone. Thanks for the reply. On 9/21/2017 at 3:37 PM, gwest_ca said: Lights are a little brighter today.
