Nothing from them yet, but my experience in the past 4 years has been decidedly different with respect to 6v batteries. My charge rate has varied from 5A when I had a cutout (2 yrs) to 7or 8A with what I've now determined is a non functioning FP regulator (2 years) and my batteries have invariably l...

Jeff, however I'm a fan of the 494 cct which, as JohnH suggests, would be a lot easier on the mechanism and perhaps less distracting for the driver ;) Luke, It's funny we've been so focused on the meter....but what about the battery? I curious if there's any research about cycling a charger on/off ...

John,
Yes, I do realize that but if it's only for a couple of seconds just to slow the transition it shouldn't really make that much difference,esp since that device is already operating at room temp, and it's heat sinked. I'll give it a try and see what happens.

Jeff

Andre, While it may seem like a good idea at first glance to drill and tap the holes for an M3 screw, there are practical and mechanical issues here that indicate that it probably wouldn't be a good long term solution unfortunately. It is common practice that the minimum recommended thread engagemen...

So it finally got to 53F today and I drove around for a couple hours with the regulator in the car. A few things I noticed - the good news is the design functions exactly as it was meant to. When the battery reaches full charge, the mosfet fully saturates and cuts off the charging. - my current draw...

For better or worse, I cut off the part of the new insulator that goes under the stationary brush and use only the portion that goes under the moveable brush. Naturally, the old insulator under the stationary brush, needs to be in good condition yet. That's one way to do it, but if you're going to ...

Yeah, Steve, thanks to YOU, I had good instruction.
And Ron Patterson's posts on the old forum are worth their weight in good Babbit

My original info on attaching the starter brush plate was incorrect. Ron recommends using solid copper rivets. More info soon.

AdminJeff

I got this question from another T'er and thought it might benefit someone else, so here goes: Hello I am in need of a source of the rivets which hold the individual brush holder on the assembly or if not available what people are using to repair it. Any help would be great. Thanks , John Good discu...

Ron Patterson is no longer doing starters or generators.

So far, I’ve tested Tonys circuit on 6 different generators now and 3 different batteries. So far so good. I’ve tried charge currents from 5A-10A. My board is on top of a Fun Projects regulator can.

Having driven with both the TL494 and LM393 regulators, my personal preference is for the LM393. The reason is simply that by glancing at the ammeter it's obvious the regulator is working. With the switchmode control from the TL494, I find I have to loook more closely at the ammeter to interpret th...

VERY interesting. I just ordered some TL431s. I’ll breadboard this design as soon as I get them.

AdminJeff.

Yes, Luke, your reading and interpretation of my post is the correct one.

AdminJeff

John, It is interesting... when in doubt, eBay. I've been eBaying since they first started in 1995. I was at Netscape in those days and a huge supporter. It's quite amazing what I've bought and sold on that platform over the years. If you think about it, the FP regulator was designed by one guy with...

FP was taken over by Birdhaven. My understanding is the FP regulator is not being produced because the IC it uses is now unobtainable.

There is obviously a constructional fault if your MOSFET is not being driven to saturation.

Yup. Tony's original "new" design had the feedback resistor on the wrong input of the comparator. I figured that out and replicated his results above with a small mod.

Jeff

Tony, Ok I’ve verified your new circuit. I had better luck with a 75k resistor for R6. I also put a 0.0068uf cap across that resistor and it seemed to help dampen the on/off oscillation. After researching hysteresis on several sites, a couple recommended this approach when in noisy environments. As ...

after a few minutes the needle swings back and forth and a couple of minutes later it drops to zero. Tony, I'm on your updated design with the single transistor switch. After I figured out and corrected the wiring on R6 to U1, pin 2, I saw the exact same thing... not very elegant. It would be bette...

Tony, I like the simplified design. I assume that you left the unused 1/2 of the op amp there "just because"? It serves no purpose that I can see...
