Adding a solenoid on an 854...

[ri702bill 8,387]

I got an inquiry from @Handy Don recently about adding a solenoid to his 854 that does not have one. The idea it to take the high amperage load out of the 3 position keyswitch to improve it's service life. There is precious little room to add one on any short frame tractor - here is what I did about 8 years ago on my 854 8 speed.using a spare solenoid from a C81...

I fabricated a metal plate to mount the solenoid so it is stood off the rear of the S/G, and not in the way of access to either the oil dipstick or the oil cup on the rear S/G plate.The wire and cables are short & tidy.

My answer on a 1067 long fram tho. Was then able to use a off the rack  five term switch.

I was hesitant to put a solenoid on my 854 only because I liked the sound of it cranking without the click. I even replaced the original tired switch with a new one. But I finally gave in knowing it's a better setup. Well, it turned out that the cranking sound didn't change a bit.

And  I see addition of the MUCH needed 15 amp fuse - 854's had none.

Here's what I did... Used a weather resistant flat blade fuse holder with cap. Added a welded strap to the non-original 702 style hoodstand brace.

@Handy Don, If you plan to use a solenoid and wish to retain the generator light you will want to wire the Generator light to the solenoid load side and  switch ignition terminal.

Thanks for the thoughtful note & diagram!

The 854 pre-dates those hifalutin accessories! It does have its original ammeter and I have added a voltmeter, but nothing complicating the simple change to solenoid from direct ignition switch. I almost went for a simple “off - run” key switch and one of those sometimes-floor-mounted momentary-contact buttons for the starter!

....just like a 702.....
