Shimming after swap?

[79Betty]

Truthfully i don't know... Looking... One to alternator and one to resistor are spliced into 1 and eye looped on starter bolt on top woth battery cable. Other goes to hei

According to my manual you should have the black from the battery to the big terminal, a red to your altenator, a red to the junction block (you call it a resistor), both from the big terminal and the purple wire to the solenoid.
What's this other wire with the eye and where is the one to the hei hooked to?

[79Betty]

Wifh the eye one goes to alternator other goes to junction block. Hei is hooked to the right terminal

Hei shouldn't be hooked to the right terminal. It should have it's own red wire from the ignition switch. THat's why your staerter won't quyit running.

I'll double check when i'm home. Weird thing is whywould this only happen after i swapped transmissions and cabs?

THe previous wiring in the other cab likely had a bad ignition run wire that the PO fixed by running to the starter. You changed that and fixed it in the new cab wiring.

[79Betty]

That would make sense. I'll check it good when at home. Been aggravating me so bad thought about going back to automatic lol. Another mind always helpS think about things

It may have the wrong starter drive in the starter seeing as you put a new flywheel and could be different from the old. It probably stays engaged because it's stuck on the flywheel.

[79Betty]

One starter come off a 77 c30, one off a 77 c10, and one off a 79k10. All 3 get stuck when starting. Btw geezer my hei plug goes into the firewall harness not starter. Starter wire on right post goes to... Junction on to right side big one. Smaller one goes to alt and firewall, included pic!

Does the wire have power in the run position?

[79Betty]

Which wire?

Well little fact. I put in my 78 k20 harness put of old cab. Plugged in ignition switch, turn signal switch and grounded it... Now only clicks... Yea

This really is a weird problem seeing as you've tried different starters and harnesses, There should be three wires on the starter the battery the cab supply and then the ignition wire which only has power on start. The clicking starter means solenoid no good but it was just working with the other harness. I think you need to chase back the ignition wire to make sure you only have power in start

[79Betty]

Idk. It's making me so mad i'm thinking about putting my turbo 350 / np203 back in just to drive it. Auto column with k20 harness just clicks... But it acts like it's trying

I wish I were there i could help you out but hard on this side of the computer. I just find it hard to believe it's not the actual starter giving you problems. If you don't have power at the solenoid when in run and when you kick the starter and it click then the wiring is fine, Know what I'm saying?

[79Betty]

Yea as that was last night lol. I took my 77 dually wiring off the motor and plugged it in to the firewall and everything else. Going to see what happens. Not like anything else has for the good lol. Will post result

Well well. With all 77 wiring, STARTER STILL GRINDS!!!!!!! Ugh! Don't think it's the flywheel since it's brand new... What else could make a grinding ugly noise?

[dfj73]

it cant be meshing with the flywheel correctly, try shimming the starter down some and see if that helps at all

[79Betty]

I'll try mortow after work n see what happens. Got a new ignition switch for column today so that eleminates that possibility all together.

if its grinding I'd think the wiring is alright

[79Betty]

Well all the wiring is from a 77 c30 which i started and drove home so i think so too. This is very frustrating

[dfj73]

I'm frustrated for you honestly, I know how it is when you just want to drive

[79Betty]

Not much ya can do but keep chippin away at it. I just hope i get it lined up before my flywheel gets fubar

Try the shims and hopefully that works. I'm hoping at some point I can get my truck out of my garage but winter is coming and the frames not even painted yet

[79Betty]

I painted mine from the motor back woth rubber paint like flex seal. Took to it awesome hasn't scratched and covered one can per side. Motor forward was covered in oil so bad water just runs off it lol
