When do you okies sleep? Lol

Whats sleep??

NEVER!!!!!!!!!

You get the new water pump on it? Is it running good? Have you drove it? How does it drive? When you cruising it to work? Are you working on it now??

[joe231]

well.....
I swapped my pump, warmed her up and set my timing to 0 degrees with the computer timing plug disconnected. it won't hardly run at 0* but it runs ok with the computer controlling timing. I think maybe my balancer has slipped. I think I will advance the timing a couple degrees and see how she runs then. I also don't have output from my alternator. It is a CS series alternator and I know it needs resistance in the "L" circuit to output. The only wire I have found that appears to go to the alternator has very low resistance in the circuit. Every diagram I have come across shows a brown wire going through a bulb in the cluster to the alternator, well guess what? I have no brown wire and no charge indicator bulb in my cluster
I guess I'm going to run to Radio Shack and pick up a couple resistors today and see if I can make it work. I managed to drive it around the block though....I knew I shouldn't with out the alternator charging, but I just had to I got about a half mile from the house and she went dead and wouldn't start I walked home (couldn't help but check out "Big Sexy" as i walked away, it looked super cool sitting there, wish I would have had my phone to snap a pic) got the '80 and jumped it to get it home. Found a couple other problems that I need to fix. The speedo is way off, so I will have to figure out what gears i have in the rear diff and change out the speedo gears in the trans. Also my fuel gauge doesn't work, I've narrowed it down to an open circuit at the tank....guess I'll have to drop the tank again.
I know it will be worth it in the end, but geezzz, the devil is truly in the details!!!

guess you posted this as I was typing

[scotts62]

oh man i thought i was the only one here lately walking!

That sucks, do you need an alternator or is it just the wiring?? I think i have an extra alternator at the shop..

May have a balancer too

I'm pretty sure it is the wiring, the crazy part is this is the correct alternator for this year harness.....I just don't know why it doesn't match any of the diagrams. All the diagrams I have found for the 87-91 R/V trucks and the 88-98 C/K series trucks all have a brown wire running to the alternator.....The only "extra" wire I have that could go to the alternator appears to be pink with a black trace (or stripe).

[scotts62]

The plug i gave you was off a 90'..

Ok so your wiring has it but the plug for the alternator plugs dont.., right?

[joe231]

no, the plug is right I believe, I just don't seem to have the correct circuit in the 'burb harness, So I'm gonna have to add some resistors to make it work

[scotts62]

Oh gotcha, sorry i was confused again..

[joe231]

that's how we roll

[WillieloRidez]

Have you thought about fixing the alternator problem by putting a one wire on it? Just a suggestion they are pretty cheap and all you have to do is run a wire directly to the battery

[scotts62]

Thats what someone else had mentioned a while back too..

All of my research has told me the one wire is not a good option in a daily driver especially with fuel injection. The "CS" series alternator will out perform the older "SI" alternators. It supplys a much smoother DC supply and is capable of 100 amps. GM changed to the "CS" due to the higher demands of fuel injection and all the electronics of modern cars. That is just what I have found online, anyway.

[JohnC]

Is there maybe a difference in alternators betwenn the C/K trucks, and the burbs? Since they were kind on different platforms at this time. Maybe that is where the discrepency is in the diagrams?

[joe231]

nope, the alternators are all the same as far as i can tell, just different amp outputs. they used this same alt up until the LS came out. and I believe the internals are basically the same, just different case and plug...oh and they put the fan inside the case too.
I can't imagine the burb having a different wiring schematic, they just add notes like only with aux heater ect. but who knows....

[Jonboy]

Joe,
I had to run a wire to switched power (from my fuseblock) and put a bulb inline to it to the wire in the plug, them the big wire to the battery. I went around all of the other wiring that was there, and it works great. My office manager and her husband ran an alternator/starter rebuilding business for years, and he set me straight. You only need the switched power to excite the alternator. I just ran a peanut bulb and socket (194) and put it under the dash. The bulb provides the resistance the alternator is looking for. Also, the bulb goes out right after the truck is started.

[joe231]

Thanks for the info Jon!
I wasn't sure if a 194/168 would do it or not. I ohmed one and it only showed 3 ohms. Good to know that's enough.
Turns out my alternator is bad
I'm headed out to see if Scott has another in his parts stash

That's probably why it isn't working right then.

[scotts62]

He is out there raiding my stash right now..

[BGRAFX]

Joe grab me some parts too!

Yeah guess so.... no wonder his project got such a kick start
