12 volt conversion wiring question

Hello all,
I am doing the 12v conversion on my 52 8N and want to get a better understanding of a couple simple concepts.

1. My 6v battery has the negative post and lead bolted to the frame and the positive post and lead bolted to the starter solenoid. Does this mean my 6v was wired negative ground?

2. I want to use my 6v coil just because it is only a month old. To do this I just have to use the resistor included in the kit, correct?

3. Anything else I should be concerned about so I don't grenade the new alternator?

4. Not a question, but I wish Yesterdays Tractors would post a video installing their kit. The instructions included didn't even show the brackets I received for the alternator. The only youtube videos I can find are for a front distributor and I have side. Also, I had to drill all of the punched holes in the mounting brackets because they weren't round and the bolts wouldn't fit through them. Chinese manufacturing at its finest....


Thanks for any help, I am 80% sure I know the answers to my questions, just want that warm fuzzy feeling before I wrap this project up!!

You will need an extra resistor. Whether or not the one that you will get in the kit is the correct one is problematic - it seems most are not. Given your uncertainty it's much easier to toss the resistor, bite the bullet, and buy an inexpensive 12V coil.

) yes, 2) yes IF it is correct value. Many are not & then it will have such weak spark that it won't start. Measure resistor and coil primary. Both should be about same number Ohms. 3) don't apply reverse voltage to it! 4) you should have used oval Chinee bolts! Ha ha
 
Your covered on your questions.

As per the bolts... I refer to the attached chart regularly. Especially in my own work.

Alright..... Got everything hooked up. Small lug on starter solenoid broke off when I tried to remove old wire. Went to trusty parts store, won't say which one but rhymes with SLAPA and picked up a direct replacement. Made in China. Turned on switch, pushed starter button and the old girl spun like a 350 small block! Problem was it wouldn't stop turning over. Luckily I was wise enough to leave the ground terminal hand tight so it only turned over for less than a minute. Should I have gotten a 12v solenoid? Nothing in this kit or the instructions is very helpful or informative. There was no mention of a 12v solenoid so I went with stock replacement. If it doesn't matter what voltage the solenoid is, then I just got a bad unit from overseas. I did try unhooking the push button and when I hook up the battery it still just keeps cranking. Any advise?

Oh, I did use the resistor included in the kit so if it doesn't have 1/4" spark I will replace coil with 12v and get rid of it. I ordered the kit form this site, I'm hoping it has the correct resistance.
 
Been researching on the site. Looks like 6v will work fine and I did buy the ST540. Could I have wired something wrong that would make it keep cranking when the push button wire on the small lug is disconnected or did I get a bum solenoid?

hile cranking in the 'stuck' mode, whack it with screwdriver handle & see if it stops. 6v ST540 works fine. A weak battery will often cause that 'stuck' situation.
 
Fresh battery, tried smacking it with wooded hammer handle, still stuck. Going to get a new solenoid this morning. Thanks for all the help and advise guys!
