Ford style ignition switch.

Tin, I never did change the switch but have a doc about, maybe it will help.  I can’t remember where I got it from to give credit.

I think the part number is <span style=”font-family: Helvetica, Arial, sans-serif; font-size: medium; line-height: normal;”>81871583.  Several places have Tham for about 15 bucks.  One example.  http://www.equipmentbarn.net/Ford-New-Holland-Replacement-Ignition-Switch-OEM-Number-81871583-E7NN11N501AB-E7NN11N501AC.html</span>

Wow that didn’t  turn out right.  Part number 81871583.  Aubrey

That part number on amazon specs, shows:

<span style=”box-sizing: border-box; font-weight: bold; color: #111111; font-family: Arial, sans-serif; font-size: 15px; line-height: 20.25px;”>Item Specs</span><span style=”color: #111111; font-family: Arial, sans-serif; font-size: 15px; line-height: 20.25px;”> </span><br style=”box-sizing: border-box; color: #111111; font-family: Arial, sans-serif; font-size: 15px; line-height: 20.25px;” /><span style=”color: #111111; font-family: Arial, sans-serif; font-size: 15px; line-height: 20.25px;”>Includes keys and nut </span><br style=”box-sizing: border-box; color: #111111; font-family: Arial, sans-serif; font-size: 15px; line-height: 20.25px;” /><span style=”color: #111111; font-family: Arial, sans-serif; font-size: 15px; line-height: 20.25px;”>4 position (Off, On, Heat, Start)</span>

OK this is ridiculous to post, search  the part number and several show

Below is the info I have on file. No experience with it.

Hope this helps

Service Advisory 6:
Ignition Switch Retrofit
Easy no
special tools required. http://www.tractoroutlet.

The ignition switch that came with your Jinma 1828
HP tractor is multifunction and can present some
problems after significant use. It can have intermittent faults where the momentary glow plugs and
starter are immediately on when you turn the key to the first position (lights). In other words, all three
posts are hot, #2 for lights, #3 for glow plugs, and #4 for starter solenoid. This will cause your 30 amp
fuse to blow consistently. A replacement switch is available through your local New Holland dealer and
was used on Ford Series 20009000
tractors from about 1965 on. Ask for Ford Part # D 5NN11N501A.
If you would still like to use a direct replacement that requires nothing other than wire for wire
exchange then we normally stock them. Ask for Jinma part number #TY290

I assume that you made sure it was not the safety switch on the clutch pedal?

FWIW, Cole-Hersee also makes two excellent alternatives to the OEM switch. One of them is waterproof. Sorry, don’t have P/N’s.
