A hot shot wire as i cll it was run from the R terminal on the solenoid to bypass the resistor to give a shot of 12 volts for fast start and hot spark. Now i am not and electrical engineer and maybe my way of doing something are shell we say barnyard engineering i try and follow the book with a few teaks here and there like i do away with the fuse and use self resetting curcit brakers add in C/V relays to take the load off the head light switch when someone want to add more lights then came from the factory since you pushing the factory switch to the max at five lights . I cringe at some of gen to alt. change overs that i have seen , Like running a 65 amp alt thru a 12 ga. wire and like the Farmer wire job that was hacked up on this 460 i am working on at this time . How these guys can sleep at night with something like this setting in a barn full of hay and fifty or so cows down below is unbelievable . [Reply]   [No Email]

So I thought I better ask you. On my ih460 the alt was bad, had it tested. The alt had come off a 73 chev pu, it was marked what it came off by someone. Soooooooo I had one that came off a 75 pontiac 400cu in. that tested good and put it on the tractor. Now i do not know what amps it is pushing thru the wires and what size alt would that tractor use? DON"T WANT TO BURN DOWN THE SHED Larry [Reply]  [No Email]

The R or I (what Fords used) terminal on the starter solenoid is a terminal thats hot ONLY while the starter is engaged and it connects direct to the coil input so it sees unballasted battery voltage ONLY while cranking fOR TH hotter starting spark, its a good system if all is well...
