If you have your old regulator housing you can purchase an adjustable solid state marine unit and place it inside so it looks just like stock. Once the solid state unit is placed inside the stock housing hook it up to the original terminals, adjust the output, close her up, and you are all set. The decals are still available from Stude International and others if you want to freshen it up. The solid state marine units are available at NAPA for about $40 The unit was in the Avanti when I bought it. The previous owner said he got it from NAPA. It came as a kit and I still have the instructions. The instructions say Prestolite Kit No. 90-2814 Electronic Voltage Regulator Retro-fit Package. The actual regulator is a Transpo unit but different from the number in your book. On the regulator it says Transpo M5-IS6A 12V-221. Transpo website is http://www.transpo.de/Catalog Once in the web site I located my electronic unit and another electronic unit specifically designed as a replacement to be used with Prestolite ALE type alternators. The Transpo site also has cross referances to all other major parts supplier numbers. My unit is Transpo P8-404A 14.2V Adjustable or NAPA part No. VR1006. The Prestolite ALE replacement unit is Transpo P8-352A 14.2V Adjustable or NAPA VR1008. The only apparent diffence is in how the connections are made. Dimensions may be different also since they did not give physical specs. The Transpo website list a number for technical support also if you want to call and verify dimensions. The site also has electronic regulators in what appear to be stock cases but again I don't know if the mounting holes are the same. Another possible question for Transpo tech support. Jason Ford jford@greenbaynet.com June 2001 ====================================================== (Another: Jan 2003) Basically, the update gives you two choices: Use the larger Transpo regulator (it no longer is able to fit into a stock regulator housing without being cut down on either side and the top.... but it is possible, and I am doing just this with one). Again, one of our members wrote to say he bought and is using this new Transp regulator and reports that is bolts DIRECTLY into the same location on his 1963 Avanti, using the original screws and mounting holes...... and works great. Unlike the Prestolite electronic conversion, this one has a set screw that lets you vary the voltage output of the regulator. The other choice is to get the Prestolite replacement, Prestolite part # #90-2814, which will fit very nicely inside a gutted, original Prestolite regulator housing. The wiring diagram will be similar to the one published in AOAI / Issue 120. ======================================= Another (JAn 2003) I put a Napa/Echlin solid state unit into my old can, and it's been working fine. It's a very small unit, so it fits nicely. It was VR-1006 ================================== The Prestolite 90-2814 is a voltage regulator kit, the regulator alone is 8-410. I had checked with Prestolite on the availability of the 90-2814 or of the 8-410 which is the voltage regulator I used 10 plus years ago and did an article on. Bad news! It has been discontinued as of 10/29/2002 --------- (Jan 31, 2003) 1 1/2 years ago, Transpo discontinued the Transpo 590 There is another company that makes an almost identical unit. but it is available only from auto-electric rebuilders. The unit is WAI #35-113. WAI is the name of the company. Go to my website listed below, go to the Updates and Qustions page, and look at the entry for 10/1/01 for information on cost and a source to order from. In addition to the article in AVANTI MAGAZINE, I show how to do the conversion on p. 87 of my book.
