I finally had a chance today to dig into the Gen 1 light issue again. Traced the alternator wires and they were all good. So then I started taking voltage measurements off that two pin plug again. Previously I had noticed I would get a stray voltage that would drop with my meter hooked up on the...

The gasket kit is a FelPro part number but napa has it listed as FPG TCS45554. This is not the gasket set that comes up when you search for a water pump but I used this P/N because It also includes the front crank seal which I had also replaced. It was more bang for my buck and I have some extra...

It has not been converted to 12v. Gen 2 has a floating ground connected to the battery directly I meant to say the drivers side alternator. I put 168 bulbs in all of the idiot lights and 194's in the dash backlighting.

So I have read all of the threads about the Gen lights I can find.. Several times. I have looked at the schematic up and down. I am just not sure where to go from here. So for some back story when I bought the truck most of the lights in the dash did not work. The Gen 2 light worked and that...

Only had it in a couple weeks but no issues. You will need to take the bolts for the pulley/fan off the old one though or buy new ones.

I just did my water pump a couple weeks ago. Purchased a new one from Napa P/N TFW 44099 It was a gates water pump. I used Fel-Pro Gasket set P/N TCS45554 Which includes the water pump gasket and the water pump plate gasket along with a couple others you may or may not ever need. I did not use...

That was my though too which is why I ended up not putting it in the back of the block. Then I thought about putting a tee fitting onto the heater core hose nipple from the crossover pipe but without taking the hose off it appears to be some sort of special bent hose fitting with no room for a tee.

Thanks for all of the suggestions. Now I am torn if I should move it or not. Good points on both sides. I guess I will run it as is for a few days and take it on some longer drives and see how it works. If the gauge never really creeps up much I will probably move it to the water pump. I don't...

Just finished installing a mechanical oil pressure gauge and an electrical coolant temp gauge on my M1028A2. The oil pressure gauge works great. I ran Stainless flex line to a bulkhead fitting in the firewall and then ran some heavy duty parker nylon tube to the gauge inside the cab... The...

Well I rewired the relay to switch the ground and it works as expected now! Not sure why they ever did it the way they did in the first place but whatever. At least it was an easy fix!

I was unable to test voltage because I have a bunch of other stuff apart I am redoing also. I only got about 1.6 ohm reading which I understand it could go through other components but then usually the resistance would be higher due to the component but it does make sense though that is why I...

I hate to clutter up this thread with more posts but on my truck one of the PO did a manual switch conversion. The controller card is completely gone. What they did was left the pink/black stripe wire attached to one of the coil terminals on the relay and then they tapped off of the 12v power...

I just installed this radiator a couple weeks ago and had this issue. I ended up putting a piece of some stiff foam on the top and bottom mounts to fill the gap. After driving a couple days I had to add a second piece to the top because the foam crushed down with the weight and heat. Seems to be...

Well after having the old girl sitting in my driveway half apart for the last week got it running again today. I replaced the radiator, upper and lower hoses, thermostat, bypass hose, water pump, harmonic balancer, new belts & overflow hose. The old radiator was definitely full of gunk. The...

Well I got the combustion gas tester today and good news the thing did not change color at all when I tested it. There was also no foam inside of the cap again this time when I looked but definitely a bunch of crap buildup in the radiator. I got the new one from Napa and it is the Spectra CU850...

I am picking up a new radiator and hoses today along with thermostat from Napa. I ordered a combustion gas tester also to test and see if I have other issues as well due to that foam being in there... Figured that pressure testing the cooling system with a leaky radiator wont tell me if there...

Here is what I found when I opened the cap...

So, Tomorrow makes one week ive had the M1028A2... And It seems a few issues have shown up! I received my new belts, headlights, air filter and dash lights.. Monday I drive the truck to work and someone tells me theres a puddle of coolant dripping under the truck. Great. I had filled up the...

Worked on the truck a little bit today. Changed the oil. Greased all of the zerk fittings. Checked all of the other fluids. Ordered a new AC delco harmonic balancer to replace the one that is on there. It does not look all that bad. Some cracks in the rubber but no missing pieces or bulging...

I was looking at the tiny tach that has the transducer mounted to the injector line but I have not yet ordered one because I can't find a definitive answer on what size transducer to get. It sounds like it is the 1/4". There is a ton of information on this forum but sometimes it does not all...
