7600 electrical wiring

[jwt27]

Found a couple loose wires on my 7600 (with 6600 engine), would appreciate if
anyone could help figure out what these are for:

Above the radiator there is a loose connector with two green/white wires.

Above the alternator there's two thicker black wires.

Behind the alternator I have:
- one round plug with a green/white wire
- one loose brown/green wire
- one round plug with a thick red (maybe red/brown) wire
On the alternator plug only one thin yellow wire was connected, and a thick
brown wire in the middle was loosely pushed in (crimped it back on, hopefully
that was meant to go there).

Below the battery is a sort of rubber stopper, with green/white and green/red
wires coming out of it. Looks like it could go to a loose plug down by the
starter? Can't reach it to tell what colors those are.

In front of the starter is a thin blue wire.

Below the left door I see a cable with two plugs: one with two thick brown/white
and yellow/white wires, and a spade plug with a thin green wire.

Behind the right panel (by the throttle) I found a cable with green and
green/purple wires with spade plugs.

By the transmission dipstick I have one loose yellow wire.

Should probably mention the bits that don't work:

- fuel gauge
- temp gauge
- front left turn signal and position light
- red tail lights
- bottom light on turn signal handle
- accessory position on key
- radio

The lights and radio are low priority, but the gauges would be very nice to
have working again.

Could this be for the brake light switch? It's not connected and the cable does reach there.

Does anyone happen to have a wiring diagram they're willing to share?

aybe you can get someone who knows to say whether the wiring for 4600 & 7600 are same or near same, as I do have 4600 diagrams.

I have an open station 7600 that needed a harness. I ordered one off eBay that was made in Turkey and nothing lined up or looked correct. I asked a master Ford
mechanic to see if he could make sense of it (because I'm no electrical genius) and when he scratched his head I sent it back. I ordered one from Agri-
Services in NY state and it was perfect, but not cheap. This is the legend from that harness; you don't have the benefit of the numbered wires on my harness but
the color codes may help. For reference, the front/rear dividing line is the bulkhead in front of the fuel tank. I hope this helps.

Thanks, had a look today. Unfortunately none of those colors seem to match
with what I have here. Thanks anyway though, I do appreciate it!

Is this the same diagram? If so that also looks very different, unfortunately.
Maybe the wiring for an x600 with cab would be more similar.

Re: that cable, it has to be for the brake light switch. One wire gets 12V,
the other has some resistance to ground. That goes open-circuit when I remove
the tail light bulbs. The switch itself needs replacing though.

Also, I measured the fuel and temp senders. For fuel I have about 240-270
ohms, tank should be close to full. The gauge does move a little when I
connect the wire, but doesn't go above empty.

On the temperature sensor I see 5.2K, cold. No movement on the gauge when
making a connection.

Anyone know if those numbers sound about right?

(quoted from post at 00:03:29 04/13/23)Same diagrams. All of the handful of senders I have experience with have lower resistance values, in range 25 to 50 Ohms max and lows of ~ 0

Alright, will replace those then. Am I right in assuming there's coolant
behind the temp sender?

If i looks anything like these two pages, I have the other 5

That does look very similar, thanks! Let me know if you need a link to upload
larger pictures.

oolant behind it...remove it and coolant flows out. send link. There is a drop-box method but I don't remember how to use it.

I would've sent a link to my personal web server but it seems private messages
don't work on this board.

I see you used imgur before, that should be fine. I think the limit is 5MB
there.

don't think I can use imgur for pdf files. I think I have dropbox share figured out and I need your e-mail address to share . I don't put e-mail addresses out here in the open, but YT has something called safe-mail and addresses are not shown. The "Send Mail" in Classic view or "email icon" in Modern View must be visible in order to use safe mail. To enable, go to "Profile" in Modern or go to "Options" in Classic and select "Modern View Options" and enable the e-mail icon. Then by Safe Mail we can get each others address privately.

Sent you an email earlier, don't know if you got that. I did enable email in
my profile so you should be able to contact me too.
