This post was updated on .
The battery is still providing lots of current.
I said *the SOLENOID* (on the starter) requires 13A to stay engaged.
The starter itself?
I think I have to go back to FTE for that..

So the Ford solenoid on the fender only needs 13A to pass through.
Iirc, the starter draws around 150?

Maybe Matthew can do a PMGR upgrade at the GTG and you can document it for the site?

I'd be willing to pitch in a few.
Heck, when I went to DB I saw the manual 460 starter was only $47

When I installed a pmgr starter back in 2012 it came with a test sheet showing a bit over 500A under load.
Of course it has a solenoid attached, and this showed 40A to pull and 13A to hold, so this is the only load my fender mounted relay sees anymore

Yipes!  YIPES!

I wonder how much torque it puts out at that current as opposed to the old style starter?  That 500 amps is surely stalled, and with the gear reduction it won't be stalled long.

Negative!

As much as I'd love to make a contribution to the site like that, I won't be making mechanical changes to the truck in the middle of a 2500 mile trip.  I'm heading down to Texas after Oklahoma, and they have more banjos than Arkansas...

David/1986F150Six has had similar responses to some significant changes that have been proposed.  And I can fully understand.

I'm pretty sure I had posted a pic of the graph there as well but I'm not looking any farther.
Iirc it was 512A.
Yes, that was 'Max' draw.

Those starters spin pretty fast.
I posted pictures of the guts (planetary reduction) in my starter woes thread.
I'm sure the reduction could be figured at a glance (count)

The standard starter I purchased today has a similar peak amperage figure.

Well, yeah!    

It's doing the same job, isn't it?

Watts are work.
VxA=Watts
Or more commonly, W/V=A

Well, sort of.  The starters have the same function, of course, but if the PMGR starter is really spinning the engine faster and harder it's going to have to pull more amps at some point.

But at least it's not through the fender mounted relay.

Sounds like a regular month around town for me.  *shrug

Doesn't keep me from going to work (or futzing around with my truck)
