I recently had a customer come into my shop at Pflieger Marine Services(419-625-0605) with a problem of a Chrysler marine 318 engine that the alternator would not charge. The alternator on a Chrysler marine engine has been obsolete (as have been parts for said alternator) for years. I was able to make a fast and fairly inexpensive solution to this problem.
Remove the Chrysler marine engine alternator. Purchase part number AR20102 at http://www.marinediscounters.com/. This is a new alternator made by Arco. It is a Delco style alternator and I am going to tell you how to make it work.
Install Arco alternator on Chrysler marine engine. Install the gray or purple number 10 wire on the large stud on the back of the Arco alternator. Now cut the orange wire with the small ring terminal off and tape it. This wire is no longer used. Make sure the belt is tight and tighten the alternator. Now go to the rear of the engine next to the starter. You will find a black box mounted on a plate and next to it will be a relay. Find the other end of the orange wire you cut and cut it off here and tape it. This wire is no longer used. Remove the small black box. It is the old voltage regulator. It will be mounted on the plate and have rubber foot mountings. Gray or purple number 10 wire that is now connected to the back of the alternator will probably be connected to the voltage regulater. Disconnect this, install a larger ring terminal on the end of the wire and connect this number 10 wire to the incoming side of the starter solenoid. The small ground strap left where the voltage regulator was may be eliminated as may the short wire that ran from the relay to the voltage regulator. This is very simple and can be done in about 10 minutes. As always, feel free to Pflieger Marine Services at 419-625-0605 for free technical advise and thank you for buying your marine parts at http://www.marinediscounters.com/. Since this posting, I now (2/9/12) have even more savings for you as I have a new line of alternaters that is 1/2 price from the Arco ones. Also, due to huge response I have learned that there are 3 different mountings to your Chryler engine. No worries simply call Marinediscounters at 419-625-0605 or email me a pic. at boatdoc@marinediscounters.com
