Bluebird86 5 #1 Posted November 3 My c125 won't run right unless I leave my battery buddy attached to the battery terminals. Could this be a regulator/stator problem or am I missing somthing stupid? Share this post Link to post Share on other sites
Ed Kennell 38,329 #2 Posted November 3 (edited) to the Does it start OK on the battery without the charger? Clean all the grounds. The rectifier base must be grounder. The ground strap between the engine block and the frame. Edited November 3 by Ed Kennell 1 Share this post Link to post Share on other sites
Bluebird86 5 #3 Posted November 3 Yes it'll fire but like crap stick the battery buddy on it and it smooths right out. Is the rectifier behind the battery Share this post Link to post Share on other sites
squonk 41,171 #4 Posted November 3 First of all how old is the battery and has it been tested? Share this post Link to post Share on other sites
Bluebird86 5 #5 Posted November 3 It was brand new has not been tested maybe I got a junk one Share this post Link to post Share on other sites
Ed Kennell 38,329 #6 Posted November 4 5 minutes ago, Bluebird86 said: maybe I got a junk one A bad battery was my first thought. That's why I asked if it starts without a charger to assist the weak battery. Go to our manuals section and download the manual for your tractor. There you will find the wiring diagrams and all the electrical components. Did this problem exist before you installed the new battery? Share this post Link to post Share on other sites
Bluebird86 5 #7 Posted November 4 This is a new to tractor I bought it not running did carb work and fuel pump rebuild new battery but as you see I skipped the dumb part never even put the battery to thought I'll take it back and have it tested 1 Share this post Link to post Share on other sites
Ed Kennell 38,329 #8 Posted November 4 Yes, do have the battery tested. I would still check and clean all the ground points. Especially the strap between the engine block and the frame and the body of the R-R. And yes, the R-R is behind the battery. Please let us know what you find with the battery test. 1 Share this post Link to post Share on other sites
953 nut 55,393 #9 Posted November 4 Have you taken a look at the ignition points? Running a dollar bill between the contacts to remove any film of corrosion can make a world of difference. Share this post Link to post Share on other sites
Bluebird86 5 #10 Posted November 4 Battery tested good so I'll move on to grounds and check the rectifier Share this post Link to post Share on other sites
BBQVultureWings 104 #11 Posted November 11 (edited) Bear with Moo-Wah for a Short moment ... stepping up on muh soap box here .... Always, Always, Always Clean the cables & All the connection points, (threads, Nuts & star washers on the starter terminal post, threads, Nuts & washers on the solenoid posts & grounds Especially the Grounds on a new to you (used) Electric start machine. This is an ecellent time for an opportunity to apply a bit of anti corrosion compound such as "No-Alox" to the threads of posts, nuts, Eyelet terminals & metal connection points on the machine where the Ground(s) terminate(s). This does a few things; prevents corrosion. obviously, dramatically slows down the electrolysis process between dissimilar metals, Makes disconnecting much easier in the future during certain testing or maintenance proceedures as the threads are now protected & lubricated with the correct compound. I shudder & cringe when people pour coke on the terminals & call it good. Terrible idea as it leaves behind a coating of sugar that eventually burns up creating carbon & creates resistance at the connection. Just use a wire brush & battery terminal cleaner & or electrical parts cleaner for this job. After All these "extra Mile(s)" Steps, We have now created a Solid Electrical System. Do as YOU LIKE or as you prefer, But after 25+ years of Industrial Electrical work (including many large battery banks in my time) these are habbits & preferences I have developed when working on MY stuff. & yes even I am guilty of not always following this to the letter. Eventually ending up needing to do it anyway. good lord this poor Horse...... Ok stepping down from muh soap box & gonna leave the poor Horse to rest in peace ok a couple more whacks n I'm done..... Having a load tester helps. The discount Non retail battery place I buy my batteries from is happy to show me the battery on a load tester before I walk out the door. I buy a lot of batteries there so the guy humors my request every time. I have sent a lot of people there & he knows I recommended him so he is really cool to me. That & the Man stands behind his work. I am really interested to hear the final verdict on your problem. You eliminated the Battery so now check that the rectifier has a good clean coonection to its mounting surface & the Bonding jumper/ground strap (If so equipped) are clean & solidly connected, or bad grounds or corroded & dirty connections... I would always be suspect of dirty connections 1st & that is the simplest & cheapest of the problems to solve. It is surprising how just a tiny amount of corrosion can cause such a big problem.

Bluebird86 5 #12 Posted November 26 Alright i finally made it back been super busy with work I finally had a moment to do some stuff... so I took all the cables off cleaned everything minor corrosion on those nothing bad made it up to the rectifier the bottom was so corroded to the mounting plate and the center bolt it took me prying it off with 2 screw drivers but with that being said everything is clean now and back together I hit the key and she's now purring like a kitten at a milk pail. Thanks for all the assistance 2 2 Share this post Link to post Share on other sites
