moe1965 717 #1 Posted January 5, 2023 I'm still trying to figure out my overcharging issues on my b 100 I'm down to replacing the rectifier. I see some very small ones on eBay that are probably for newer style tractors and other sights but don't know if they are all the same or specific for every application. Any how pictured is the one that is on my tractor any ideas where I can find a proper replacment. Thanks in advance Share this post Link to post Share on other sites
953 nut 51,539 #2 Posted January 5, 2023 The jungle site has them. https://www.amazon.com/DB-Electrical-AKH6001Rectifier-Regulator-Engines/dp/B019DHPM44/ref=asc_df_B019DHPM44/?tag=hyprod-20&linkCode=df0&hvadid=198060922766&hvpos=&hvnetw=g&hvrand=9475919435455115152&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9010285&hvtargid=pla-350103303819&psc=1 2 Share this post Link to post Share on other sites
peter lena 8,038 #3 Posted January 5, 2023 @moe1965 agree with @953 nut on availability , would also detail in and verify ,related wiring , all connections and grounding , grounded mine to my battery ground cable/ bolt point , with a 10-12 ga wire going directly to that rectifier base . DO NOT TRUST ORIGINAL GROUND AREAS. typically rust / corrosion gives you problems . make up a alligator clip wire lead , as you build . insuring function . also connect that ground to your headlights . pete 1 Share this post Link to post Share on other sites
pacer 3,159 #4 Posted January 5, 2023 Yeah, that one shown is - probably THE most common one on MANY of the horses. Not a bad price either. That dang ammeter will too often cause a short which will often blow the rectifier --- anymore, one of the first things I do is to get rid of that ammeter and replace it with a voltmeter..... In my experience, seeing 16-18 volt showing on the volt meter is fairly common, and around 14v are where they stay. 1 Share this post Link to post Share on other sites

Have you tried running a separate ground from the negative battery terminal up to one of the bolts that holds your current rectifier? Do you have another tractor with a known good rectifier in it? If so, it would be worth the time to swap them and see what happens. 2 Share this post Link to post Share on other sites
peter lena 8,038 #6 Posted January 5, 2023 @ebinmaine ever since I added the enhanced grounding to my stuff , the electrical issues are gone , amperage gauges , snap to attention ,and charging is consistent. anything I suggest has hours on it , once verified , add it to the others , take advantage of a repetitive failure and make it a strong point , love doing that , sparky , pete 3 Share this post Link to post Share on other sites
peter lena 8,038 #7 Posted January 5, 2023 @pacer don't have any volt meters , might try one , have one that fits in the round dash hole ? pete Share this post Link to post Share on other sites

There used to be many choices that were very similar to the original ammeter, but.... was just looking and didnt see any like that -- there are several variations of these that are the 2" Last couple I bought I just used one of the other several variations on the meters...... Caution, they are expensive ... some up to as much $20!! I actually found better choices on the jungle than the bay. 1 1 Share this post Link to post Share on other sites
pfrederi 17,129 #9 Posted January 5, 2023 This one I would not recommend. Bought it to put on a friends Ford 80. Easy to hook up fit in the existing ammeter hole fine but is very inaccurate.. 1.5 to 2.0 volts high all the time... get what you pay for I guess. 2 Share this post Link to post Share on other sites
peter lena 8,038 #10 Posted January 5, 2023 @pacer thanks for the reference , will do some searching , pete Share this post Link to post Share on other sites
pacer 3,159 #11 Posted January 5, 2023 @pfrederi The last two I got were similar to the second type shown and they both tend to read a bit high at first. - 15-18v when a meter will show the typical 13-14v, but it doesnt bother me, its still letting me know I'm getting a good charge, and they will creep down as I start using to around 14-15v. 1 Share this post Link to post Share on other sites
peter lena 8,038 #12 Posted January 6, 2023 @Beap52 problems are rarely a one and done fix , usually related to combined fault points . usually do a complete rundown of how it works and improve any spot that needs help . that electrical grounding needs a more secure set up , if you just think that you can always have a ground / connection thats the issue . that battery cable ground bolt pont , is an excellent place to attach to for engine rectifier , and also on to headlight grounding , charging also gets better and lights are bright . have replaced a lot of original wiring , removed tight bends , chafing , corrosion . verify and check each step , only some ideas .pete Share this post Link to post Share on other sites
peter lena 8,038 #13 Posted February 5, 2023 @moe1965 note 1st / second pictures , yellow electrical lug on bottom of rectifier bolt ? that also is attached to my headlights , all coming from a lead battery cable from battery ground to engine / frame corner , amperage gauge snaps to attention , and instantly is on chg after start . try it out first with alligator clip test wires , then make it solid . should warn you , if you dare to do what I have done , the naysayers , will tell that you cannot do that . then again my 3 horses regularly start and run fine , pete Share this post Link to post Share on other sites
