![]() As you can see, these are 10ga wires where everything else is 16-18ga. This wire might be black, but it faded over time. They are a lot larger than the others, and one is this red one I'm pointing to with the screwdriver.Īnd the other is this tan wire. There are two wires that pass through the connector that go to the ammeter. Then, (not pictured) you add the voltmeter with switched ignition and ground. The ammeter gauge is on the top right.īasically, you have to re-route the alternator charge wire away from the bulkhead connector and to the starter relay's positive stud, but maintain power to the dash components while getting rid of the weak connection at the bulkhead. A while back, I already modded the cluster itself for the voltmeter gauge (had to grind down the mounting posts in the cluster) so this should be simple. I've pulled the cluster on this thing so many times that I could do it blindfolded in my sleep. So I gathered my wiring stuff and got to work! Way back on page 1 of this thread, there was discussion on why it should be bypassed on these trucks, and with a higher amperage alternator getting swapped in, plus the EFI taxing the 40+ year old wiring, it was time to get it done. Also, there was one thing I needed to do to the truck itself before the swap could happen, and it's been something I've been putting off since I brought it home: bypassing the stock ammeter and replacing it with a voltmeter. I've opted to do it at a friend's house who has a shop with a lift to make things easier, so getting his schedule and mine aligned has been a challenge. ![]() It's been about a month since I finished piecing together the Magnum 360, but getting time to do the swap has been tough lately. While things have been OK for 40+ years, I'd anticipate the higher output Magnum alternator will turn things to goo unless I fix that situation. Once that's done, all that's left before the swap is to finally bypass the ammeter circuit on the truck itself. For the ones I did install, I coated the inside of the bolt hole and the splines of the plugs with RTV to avoid leaks. D'oh! So another set of intake gaskets are on the way and I'll take care of that by the weekend. In other news, I tried installing the little intake plugs supplied with the intake manifold that plug the LA-style angled bolt holes and immediately realized that the manifoid needs to be OFF to do some of them. From what I'm finding, the pressure lines have metric fittings on the new pump and standard on the original, so I decided instead of making a line, I'll just swap pulleys and run the stock unit. Aside from disassembling for painting, I need to swap my original pump onto this bracket. ![]() The pulley puller I bought worked great, as you can see. (Yes, the paint is still wet on the pulley it laid down a lot flatter when it dried.) So yesterday, during my lunch break, I pulled that power steering bracket apart and got things painted. I've been trying to turn wrenches on the 5.9 project every day until it's ready.
