In Mid September of 2010 I happened to see a repeat of the show where Jay Leno did his 66 Toronado and had an instant remission of the disease which resulted in my purchase of a 1969 in very good condition.

CS-130 Alternator Upgrade

Postby xgecko » Mon Sep 26, 2011 10:56 am

I found that the electric fans I installed really crushed the voltage levels with the original 10DN type alternator. After some investigation I determined the simplest solution was to upgrade to a CS-130 style internally regulated alternator and after a fair amount of looking around I found this unit that was originally specified for a 1988 Chevy Caprice Wagon with the Olds 307 engine:

I installed it yesterday in a few minutes using this harness (Delco DN to CS - Part # W315CS):

It took just a few minutes to remove the old alternator, find a bolt to replace the original upper bolt due to the new alternator having no threads in the small ear and installing the wiring harness adapters (they provide a jumper for the Voltage Regulator connector that jumps two contacts; you can also jump these inside the case to maintain a stock look if desired). The result is rock solid voltage at any engine speed with or without the fans cranking. I highly recommend this upgrade for all situations as it is just a much better unit that provides better voltage at low engine speeds while providing 105 amps.

It is a good, inexpensive and simple upgrade that significantly improves the electrical system.

You can even keep the stock look by shorting the internal contacts in the regulator.
