7V Regulator

[Cookie]

I was putting a piece of aluminum strip on for cooling and then potting them in various containers, no problems heard of.

There is not a need for the capacitors for voltage balencing. And 99.9% of the time when one of these transistor based regulators fail, they go open and you have no output. But the old Points regulators can fail closed and then 12 Volts do hit the gages.

A LM317 is a nice Chip regulator. By changing the risistors values you can make a 12 volt battery charger for solar panels that output 18V to 30V DC. By bridging them you can get over 10 AMPs of output. I have build a few solar powered battery banked backup units.

I think I will just spend the money and stay OEM on this part, the gas gaguse showsmfull when I know it isn't and the temp gauge is stuck on H whe I know it is not HOT.

I'm not sure you can get new OEM anymore. And used one's would be hit and miss on working. I have gotten some from an ebay seller called roberth9. They work very well and price isn't bad.

Too far gone from stock but it works. I will concentrate on my cooling system instead.

The gas and temp gage do not work properly but I can live with those for now. I knew that when I bought it.

Thanks to everyone for the great info. I would never have figured out the problem, let alone the solution to the 2 gauges both failing. I went with torgo's solution of the mouser part. Very inexpensive solution, and I can say it works great, with no extra resistors or other stuff to assemble. Very good for those of us with only moderate electrical skills. This was easy for me! Mouser was great to deal with, even to Canada, I recieved my package in a week using the least expensive USPS option, total cost including shipping was about $12. It's soooo nice to have those gauges working again!

Just acquired some 7volt regulators from Mouser, (#BA17807T's) & have a question, does it need to be mounted to a heat sink of some sort for cooling? Or will it generate enough heat to be a factor?

Finally got around to making up a couple for my two 84 standards, as the trial one with not as nice a solder job has been working great. Very pleased with the updated version, nicer solder job, plus a second piece of shrink wrap, to cover the pieces on each leg of the regulator. Looks pretty nice, & really appreciate the input about this, called to see if needed a heat sink of any kind & was told not at all, not much heat generated here.

Could not bring myself to pay $40 X 2, when 3 solder joints on each one, shrink wrap, & crimp connectors, on end of wires to plug in & your done, for WAY LESS than $40.

Another source for the 7V regulator is Murray's Carbs. SidecarBob helped me with the link and info. Very good price, 1/2 what the other option was, $20 +$3 shipping. It is professionally packed into a plastic case with epoxy or something similar sealing it all up. Good price, fast shipping, and better yet I didn't have to do a bunch of soldering and remanufacturing the old one. I just had to change the terminal ends and it plugged right into the electrical system of the bike. I had a couple of questions after I got the regulator and Murray was quite responsive in answering me.

My temp and fuel gauges are kaput. So I just ordered 2 of the BA17807T's, couldn't pay $8 shipping on a 1.50 part, so it felt a little bit better ordering 2. I'll build them both and test them out, if someone would like the 2nd one let me know and for which bike. The connectors are different across different years, I'll try to post up pics and build info along with a parts manifest list from Eastern Beaver if you want to build your own when I have the time.

Thinking when all is said and done that if you can't find the parts locally then shipping costs makes this project kind of expensive - the most cost effective option might be to order the $15 part from Dimension Engineering with $3 shipping and then it should be simple to adjust it with a multimeter for 7v DC
