power steering cap alternator bracket conflict and starter wiring question
first of all i really appreciate this forum. I have loved C3's since 10 years old and vowed to one day have one...now at 50, my 1975 restoration is getting closer...i am not the greatest mechanic but it is enjoyable to work on and fix things...thanks to all in advance for your help on my questions...Vette lovers are friends no matter what year.
question #1: I installed my new power steering pump and it has the same problem as the old one; there is not enough clearance to take the cap off to add fluid because it hits the alternator bracket (pic attached), even the old one with stock cap instead of chrome one was too tight to take off...i know GM didn't design it this way and i am baffled why this is the case and how to fix...?
question #2 attached is a photo of my new starter and i was wondering if i have all the wires in the correct locations as i lost my little diagram i made. i will redo the bad blue taping job : )
peace fellow Vette lovers

hard to tell from the pictures, but is the pump in the correct location? meaning is the belt too short and it is too far CCW?
that big cap is likely no help either.
post a pic a bit further back to see the bigger picture maybe.
for wiring, the main power wires to the batt. lug, and the start wire to the S terminal. not sure which is which just hit the key with the S terminal off and a test light on that wire to make sure it is the correct one.
The pwr steering belt I used was a Gates XL 7365. That one is long enough to allow the pump to be moved outwards enough to access the pump cap without pulling the alternator bracket.
Hi Bluesy,
Something is incorrect at the starter.
Battery terminal and two REDs are correct on the top big solenoid terminal,
The other red on the small outside terminal is not correct. (Looks like a quick disconnect).
You should have a Purple wire on the small inside (S) terminal.
1975 should have an HEI distributer so NO yellow wire.

What belt do you have for the ps pump?
I had a 9365 but could never get the cap off until I swapped it for a 7365. (I am told a 9375 would also work.)
thanks...i have a GM 9433622 Replacement Belt...i got the part number from my assembly manual...is the 7365 a little longer? i think if it were longer the power steering pump would angle to the right somewhat allowing removal of the cap. The problem i had with the belt i have is i could barely get it on with the pump all the way in the loose position. thanks for your help !

thanks so much i really appreciate it! i will have to look for a purple wire under there...on the red on the small outside terminal (quick disconnect), where should i place that terminal? i don't see it on the diagram

I think your problem is the belt, its too long. Gates 7360 is what its calling for on the web.
thanks...i have a GM 9433622 Replacement Belt...i got the part number from my assembly manual...when installing i had thought the belt maybe too short as i could barely get it on with the pump al the way in loose position
The pwr steering belt I used was a Gates XL 7365. That one is long enough to allow the pump to be moved outwards enough to access the pump cap without pulling the alternator bracket.
belt i used #9433622 is 15 .44 x 36.07in OC...i am thinking a belt an inch or two longer will solve problem as i barely got this belt on in pumps loose position...i wonder if GM changed from what the assembly manual states and not sure which belt to get as there have been a few recommendations for diff part number belts...thanks again to everyone on here!
# 7365XL Belt 15 .44 x 37.07in OC
#7360 Belt 15 .44 x 36.57in OC
i think so far #7365XL may be best choice?

Hi again,
From the factory nothing was connected to the 'R' terminal.
When you turn the key to START 12 volts is sent (on the purple wire) to the 'S' terminal and the starter turns ON.
For the few second that the starter is ON the 'R' terminal gets 12 volts.
Once the key is turned to RUN there is no longer 12 volts to 'R or S' terminals.
Test the q/d wire and see if it has 12 volts with the key on and off and maybe we can figure out what the PO was thinking. For now remove and tape it off.
One last thing:
There should be a BLACK wire at the starter, it is a ground wire for the fan and wiper motor, attach it to a bellhousing bolt.
hey everyone, i disconnected my wires from starter and labelled the wires with numbers so i can better understand and communicate what i have...my old starter worked with these wires before
#1 is the big cable i see where it goes
#2 is a red wire going to a quick connect...not sure where it goes?
#3 looks like a black wire going into a plastic (insulator)of some sort and comes out red...not sure where this goes?
#4 is red or orange, goes into plastic and not sure where it goes (I am pretty sure #3 and #4 were tied together under the same terminal which i replaced but i could be wrong : )
#5 wirenut is just a red wire i spliced on to a black wire which goes to a ground by transmission, like before.
i don't see a purple wire anywhere as mentioned in some replies
thanks again everryone i just dont want to ruin my new starter or battery : )
(and i see i need to fix the near break in #3)

At a guess i would say 3 and 4 connect to 1. Same place as you had them. 2 goes to the terminal marked 's'.
On a slightly different subject, some of that wiring is starting to look old and brittle. Might be a good idea to replace it and get rid of whatever bubba has done.
I would venture to say that the large wire that you have labelled 4 goes with the battery cable to the larger post on starter. Then you need a wire to the s terminal (start) which is a purple wire that should come from your ignition when it is in the start position. Other wire you need goes to the r terminal (run) and what the yellow wire does is send 12V to the coil for start up because as soon as you release the key in the ignition switch, that circuit shuts off and the coil is fed through the resistor from the ignition switch.
I would follow the wire back to the coil and identify it first. Then the other is to the s terminal. If you have a wiring diagram it will make this easier for you. Who put the two wires (2 and 3) in the large connector?
Did your can start before you mixed up the wires?
If so maybe the #2 wire with the disconnect might be spliced into the purple and belong on the 'S' terminal.
Hook up the starter and battery wires but leave the #2 wire disconnected.
and see if you get 12 volts when you turn the key to START.
