Attachment of Harness Along L Inner Fender; Alternator Ground Wire Attachment

[Mark E.]

I'm working on the engine wiring and vacuum line routing for a 1970 LS-5. Two questions:

1. How is the alternator ground wire attached to the alternator? 1970 AIM 12-A7 shows the lock washer goes on first, then ground cable, then cable bracket, then bolt. That just seems odd, and I don't recall seeing a car like this. It seems the order should be cable bracket, ground cable, lock washer, bolt.

2. How are the vacuum lines attached to the left inner fender? AIM 12-A7 shows two clips on the inner fender, and that's it. The 5th edition of the 70-72 JG p. 169, fig. M 25.5 shows the same thing, with the lines drooping down below the horn relay. The first photo below shows my car with basically the same thing. But the second (upside down) photo shows a clip on the hose harness near the horn relay with a "push pin". And next to this clip on the inner fender is a dimple (visible in the photo, near the loose hose clip), Is this a coincidence, or should the dimple be drilled and the clip attached to it? This inner fender has been worked, so the dimple may have once been a hole.

Thanks folks.

1. Typically I see a star washer against the alternator case, then the strap, then the wire, with the bolt last. The star washer provides ground into the case, strap and wire. Very typical.



Picture is of a 70, it uses two clips. No third clip.
Hope this helps.

Thanks Gary. Very helpful.

So you're saying washer-bracket-ground wire-bolt is typical. And what the AIM shows isn't (washer-ground wire-bracket-bolt).

I looked at another 70 before I left the house this morning, it's as I posted last night. I'll look at others in Laughlin, Nv.
