12 volt solenoid wiring

Im up a stump.
When I replaced the steering gear i decided it was probably a good time to re do the dubious 12 volt conversion that came with my 641.
I totally rewired with soldered connections per some of the published diagrams. My question is;
How do i preserve the interlock button safety feature with a standard 4 pole solenoid. It would be very simple to wire a key start between the two small terminals, but that would defeat the gear interlock.
How is the best way to wire a 4 pole solenoid, or is there a better choice of solenoid. Thanks in advance

ell, IF, you have the correct 4 pole solenoid, then one small terminal receives power from ignition sw, just as does coil, and the other small terminal receives ground from the gear interlock safety sw. IF wrong 4 pole solenoid, then it will not work.
 
i *believe* an st541 is an isolated base 4 poster.. but someone else should verify that.. I don't have my scratchpad / notebook with part numbers with me here at work.

awhtx, jmor or john in la may be able to verify or correct that #

I had the same problem with my 640. The simplest thing to do is just stick a 6 volt 3 post solenoid on it. Run the wire from the small center post to the safety switch.

coo.. so my memory is at least working a lil. I try to remember the 6v numbers as they can be used on 12 in a pinch. lets see.. st53 for an 8n? how am i doing? :)
 
the 6v solenoids will work on 12v.. and of course the 12 will as well.. but won't work on 6. so you could get either if theyhad them.. if on a 12v system and they have both.. get the real 12v one just because...
 
Local mom and pop auto parts store had a solenoid.
Unlike chain stores he didnt have to ask what model of car. Told him I needed a 6 volt ford tractor solenoid and he went back and got it. Enjoyed a good conversation with one of my old friends while we were sitting on stools at the counter. The zone dont have that, I bet.
The chains dont have counter stools..they want you to get your stuff and get the hell out of the way so they can sell someone else something.
Thanks for the advice and excuse the rant.. Im turning 58 this year and I'm getting grouchy...
