Anyone have a stator lying around that they would want to part with? email me at my address ragbrian at gmail dot com and let me know what you have (especially during the transition period for this board). After a nice 100 mile ride yesterday, my battery was nearly dead as I pulled into the driveway. My stator has low output (12v - 12v - 5v) as measured between the yellow wires. While I have continuity on all windings, I see that there is low resistance (approx. 1500 ohms) to ground, so a lot of voltage is being shunted off.  The high voltage windings are working fine, which is another reason I am glad that the early models have this feature! So....time for a stator rewind. Until it is replaced, I am working on a circuit were I can bring along some SLA batteries and use them to run things until they are low, then switch in the main battery for lighting. If I actually get this to work, I will post the results, and may even offer my services to a buddy to repair his bad stator in his Moto Morini 500! Thanks!

While we're on the topic, how different are the stator cores between the CX and GL?  Since I'm using the Ignitec, I won't need the ignition windings.  Would it be feasible to rewind one as a charging-only stator?

Randall they aren't that different but you're going to want to use a gl stator core because of how the high and low circuits are wired on the cx stator. If you need one. http://cgi.ebay.com/ebaymotors/1981-GL500I-Silver-Wing-Stator-charging-alternator-_W0QQcmdZViewItemQQhashZitem1c127261d7QQitemZ120568570327QQptZMotorcyclesQ5fPartsQ5fAccessories 1979 CX500 Supertanker ATGATT makes riding a bike like a sled easier.

A check of web site shows only a couple of mentions of the older style rewinds. I will also add my $0.02 worth of knowledge when I get my worked on. Having to trickle charge the battery after every ride kinda sucks! RAGBrian 1978 CX500 Standard (Running...) | 1982 CX500C (donor) | CB360T (NOT running) | CB350G (donor?)    Report

He's done a comprehensive write up of the project stator rewind he did. Skip & BlindStitch, I found Hann's site awhile ago while researching CX's. A great site for mods and repairs. Thanks for the recommendation and I bookmarked it as I forgot his URL. Yes I have read the stator rewind article previously. In it he notes that the high voltage windings fail on the stators for the CDI bikes and makes the recommendation to switch to the ignitech module. My problem is the opposite-not enough voltage on the charging windings to keep the battery charged! So, I will play with the stator rewind and see what I come up with. I have a long back ground in electronics, and have wound my own toroidal transformers for radio receiver circuits, so winding thin wire is not an issue for me.

07-11-2010, 7:02 PM Blindstitch Joined on 03-14-2009 Greenfield Wisconsin Posts 9,838 Re: Need stator for my 1978 That's what we are saying. The current cdi stator  uses 3 circuits. 1 for low, 2 for high and 3 for charging. Well the ignitech kills the need for 1 and 2 taking its power from the battery like the Gl's do. 1979 CX500 Supertanker ATGATT makes riding a bike like a sled easier. Quick Reference    Report

07-11-2010, 8:33 PM Blindstitch Joined on 03-14-2009 Greenfield Wisconsin Posts 9,838 Re: Need stator for my 1978 There are probably several threads. Advantages. The cx stator only puts out 170 watts vs. the gl 250 watt stator.  Yes the gl stator fits just right. Circuits 1 and 2 are fun. The low one is normally the second to go. If the high circuit goes you won't be able to drive over 50mph. If the low goes then the bike won't even start.  Eliminating these makes a lot of sense. The one thing that sucks about it is that with the high and low circuits can actually power the bike if the battery dies or the main fuse snaps.  But if you are using the ignitech then these two circuits won't be used for anything. It's win win especially if you already have the ignitech. 1979 CX500 Supertanker ATGATT makes riding a bike like a sled easier. Quick Reference    Report
