CS 144 Alternator Electrical HELP!

[patmckinneyracing]

I have yet to make the conversion yet but this is what I'm trying to figure out. There is an "adapter" harness to go from an SI alternator to a CS alternator. Some are specified as those for cars WITH a warning light or those WITHOUT a warning light.

My car still has the sweep style gauges (No voltage gauge), so I'm sure it has the warning light that shows a picture of a battery. Do I need the inline resistors? The two wires leading from my alternator are red and brown, while the brown wire leads back into the cockpit. I've read that there needs to be at least 35 ohms of resistance in the alternator wires.

I have the plug from cadillac that I pulled this alternator from and plan on patching it in.

I read from this website http://www.novaresource.org/alternator.htm that the warning light bulb provides enough resistance and an inline resistor is not required. Any input appreciated.

I have gauges and I got the adapter from Napa which has a resistor in one of the wires...for an idiot lite (nothing personal) you don't use a resistor...

non resistor adapter
NAPA: ECHEC80

if you decide to put in a gauge
NAPA: ECHEC82

I know it's been asked before but what vehicles does the cs144 come on? And besides the pulley, is it a bolt in and go?

They come primarily from cadillacs. I know the early to mid 90's cadillacs have them and you need the one that has the two mounting holes 180 degrees of each other. Look at a picture of a CS130 and a CS144 so that way you know the visual differences when you go to the yard. From what I've read, you leave the alternator brackets lose, bolt in the alternator, then tighten the bracket bolts. So yes they fit right in.

I'm trying to find a turnbuckle to use as an upper alternator bracket.

Delco CS144 Series
140 Amp, 12 Volt, CW, 6-Groove Pulley
Used On:
(1996-94) Buick Roadmaster 5.7L
(1996-93) Cadillac Fleetwood Brougham (RWD) 5.7L
(1996-93) Chevrolet Caprice 4.3L, 5.7L

(1995-92) Chevrolet Lumina APV Van 3.8L
(1995-92) Oldsmobile Silhouette 3.8L
(1995-92) Pontiac Trans Sport 3.8L

I got mine on the engine I bought out of a 94 suburban and used the serpentine set up so I'm not sure how they fit the non serpentine set up

They should fit right up minus the pulley. Thanks for the list. There are quite a few of those vans at the junk yard, so I might get lucky!

that turnbuckle was bought at lowes for about $3

That looks pretty good and doesn't cost the 40-50$ that summit wants for theirs. I'm just not a fan of how our stock alternator brackets look.

I like it! Wait is that one of those custom Dasani over-flow bottles?

That's not my car if that's what your thinking...I just stole the picture to give pat an idea..
