Ronwheel82 0 #1 Posted September 16, 2017 (edited) So I just got a new ignition switch for my 1992 416 h and when I installed it my test switch crumbled into pieces now I can't get it to fire up Edited September 16, 2017 by Ronwheel82 Left out model Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,474 #2 Posted September 16, 2017 The test switch is powered by 12 volts from the battery so make sure the red wire is not shorted to ground. You likely blew a fuse if it did short. The light panel does not have any influence on the tractor wiring. You can unplug the circuit board if you want. Garry Adding - make sure your new ignition switch has one terminal identified by the letter I (eye). There are identical switches except for a letter M on them for the ignition and they are not correct for this model. 1 Share this post Link to post Share on other sites
rmaynard 14,851 #3 Posted September 16, 2017 When Garry said "The light panel does not have any influence on the tractor wiring."I would add that that is true unless the panel or the 9-pin connector is shorted, in which case it could cause a problem with other tractor wiring. 1 Share this post Link to post Share on other sites
Ronwheel82 0 #4 Posted September 17, 2017 I checked to make sure red wire was not grounded and my 25A fuse stopped blowing, but now when I took up the battery I get nothing when I turn the key. Any thoughts? Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,474 #5 Posted September 17, 2017 Pto OFF? Try pulling it farther into the OFF position while cranking. Transmission in neutral? Those 2 switches control the power from the S terminal on the ignition switch. 30 amps fuse OK? It powers the start relay and the above two switches control it.
