Re: Alternator question

When you get your ACDelco PT2145, use an ohm meter to measure how many ohms the resistor is, and please let us know. Many old threads about doing this mention all different resistor values and going to Radio Shack for them, so I wonder. American Auto Wire has an adapter also, and I don't know if it has the sense wire included but it does have a resistor on the L wire. Their resistor is 510 ohms according to a tech guy that wrote me back in an email. They say in a white paper on their website any resistance between 35 ohms (5-Watt resistor) and 500 ohms (0.5 Watt resistor) is fine. I wonder why the big range.

Re: Alternator question

I will certainly do once I receive harness and hoping it is within specs

Re: Alternator question

I usually go anywhere from 150-300 ohms.

Re: Alternator question

I'm glad this thread appears to be helping other people. I thought seriously about making a streamlined how-to for dummies like me, but the I can see that most people are leaning towards the CS conversion, so I won't bother.

Like a dummy, I reinstalled my coolant overflow over the terminal box that I used near the junction. I had wanted a pic or to to show how clean the installation is, and how the box looks, but the screws are hard to get to, and I don't feel like removing the coolant overflow just to take a picture. Suffice it to say that it works great and looks very tidy.
Thanx again to all that helped.

As an aside, shingles rash is almost gone after nearly 4 weeks. Pain remains. I have almost forgotten what it is like not to be in pain If you are over 50, do yourself a favor and get the shot. They do it at the pharmacy, you don't even have to get an appointment or go to the doctor. Supposed to be 90% effective.

Re: Alternator question

Alright so I got the Part PT2145 GM(88861073) and according to the reading its 511, so I am just assuming this reads 511ohms resistance , I did this on two different testers and got the same result so this would pretty much be correct to what dmjlambert had said

Re: Alternator question

That looks good. Your new alternator will probably bolt in and work fine with this adapter. Please let us know.

Re: Alternator question

Looking at finish installing tomorrow, there is no ground post on the CS130, is it just grounded thru the Case and bolts or am I missing something here ?
Cheers

Re: Alternator question

I think because the regulator is internal that part of it is not so critical like it was on the others where the regulator had to be grounded to the alternator.

I am using a CS130 without the resistor, just the indicator lamp to the L. Apparently the alternator life may be compromised but it has been on for about three years now and working good. I'll have to find the time to parallel in a resistor.

I'm pretty sure i understand the process minus the swapping the alternator from driver to passenger side.

is this a must? and if so why?

Re: Alternator question

Alrighty installed CS130 and working excellent, showing a continuous 13.5 volts loaded or no load, I had a bypass plug for generator style setup so used that, generator style plug to SI plug style to CS style plug and all good , and routed a new 10 gage wire from altenator to battery

The only difference would be wire length

If it's set up to work (brackets, etc.) no reason to move it in the least.

Driller - what about a photo of your shiny new CS 130 installation for us readers?!
