I see what you mean. I had to go double check, I do have about 1/2" of clearance between belt and tensioner. I thought it might stretch a little after the engine has run.The non-AC idler is a smaller diameter however more importantly, it's mounted much lower. Your belt is a lot closer to the tensioner.

I could see maybe if the alternators were different but the descriptions imply otherwise.I actually do hope to put A/C in this truck. I have the compressor that came on the motor and hopefully it's functional.i see the belt problem ....... needs a YORK air compressor kit there were the a/c pump would be .
and as said you didnt need that whole delete bracket and pulley setup . just the lower pulley and belt like the other posted a pic of .

Can't be a perm magnet starter to jump from main lug to signal terminal.Wiring not right
The trigger wire is actually is connected to the battery lug on the starter and it gets its power from that. So when you trip the remote solenoid and it sends power to the starter which then also trips the trigger.
Make sense ?
I understand your POV on adding a potential failure point, however I have seen International trucks with 3 relays in series for the starter engagement power. I have only had to replace one or two in 16+ years.Why would you add another failure point? Two relays are twice as likely to fail as one. I am not a fan of the whole Ford external starter relay deal.
My BIL spent an hour in the snow changing his F150 starter 15 years ago, I walked out when he was about done and he hits the key and nothing, he was quite disappointed. I said, turn the key on and leave it on, he did it with a puzzled look. Then I proceeded to jump the relay on the firewall with a metal scraper on the end of his wire brush, and it started right up, the look on his face was priceless. He carried that wire brush with him until he could get the new part.

I have to change the routing of the cables between relays and I'll need longer cables. If I can save a bit of heavy gauge wire, that would be a plus.If it has been working, why F with it?
You will only want to eliminate the excite wire to the starter for a short jumper if you DON'T have a permanent magnet gear reduction unit. Otherwise, you get run-on of the starter motor after releasing the key.
So an old school Delco unit it fine with it, but not a permanent magnet unit.
Been there, done that.
The reason I put the relay in was so the battery cable to the starter wasn't always hot. It was inspired from watching @ktmoutfront boil down a battery on the trail when his cable shorted out on the frame.Why would you add another failure point?

You mean the ignition switch in the column? That wasn't it, it was the external relay on the firewall that I bypass jumpered with that piece of metal. Once he replaced that it worked fine with the same ignition switch. The old starter likely wasn't even bad. This was probably a late 90s or possibly early 2000s F150 with the old mod motor that would blow coils and head gaskets back when you still had to hold the key down to crank it.You BIL truck wasn't the solenoid that failed it was the ignition switch.
The dual relay, allow for more current to the starter solenoid, esp when hot. The original path for the starter signal current is long and many connections. A couple of decades later voltage drop and current drop across the many connections, only needs to close the 1st relay in a much cooler spot.
All modern cars and trucks are this way now. Most will crank until start with just a bump of the key, or your quick push of a button.
I think for that you would want a master cutoff like they require in NHRA so it kills the engine and all electrical power with one switch. Thats required if you move the battery from the stock location, or once you go faster than 10 sec or 135 MPH in the quarter.I have to change the routing of the cables between relays and I'll need longer cables.

If this is an early triton motor 97/98 up. They have a solenoid gm style starter. While I have R&R'D hundreds of them , only a handful were bad. I did not find it a difficult job.You mean the ignition switch in the column? That wasn't it, it was the external relay on the firewall that I bypass jumpered with that piece of metal.

I agree on the rest, most modern vehicles the ignition switch just gives the computer the signal to start the car now. And I agree on the older stuff as well, if you have a weak ignition switch it may not give full power to the battery, but some wiring diagrams above aren't just supplying more direct power to the battery, they are adding another interrupt to the main starter cable. Your diagram eliminated that.
Did they move the ignition switch to the firewall on the passenger side? That's where this part was, whatever it is called, looked like a large relay to me.If this is an early triton motor 97/98 up.

Mid nineties ford's I had to replace multiple ignition switches on tall the trucks several times. The 98 up only had 1 ignition switch recall, and they got the redesign right that time.
