Today after mowing for approx 60 mins the PTO failed to engage. Brand new battery 3 weeks ago snd it finally ran down after not being charged. I charged it back to 12.60 DCV and left a new trickle charge on it. This confirms the VR is toast.
Yes I will remove the VR and reinstall it to ensure ground to the chassis. I did check with the dealer and the machine is still under warranty. So that’s a positive start!
Thanks Bert. I will look for the grounding strap on Saturday when I get back to the mower. Any diagram of where that ground strap is specifically located would be an immense help to me. I could not find it on any of the Briggs exploded views or the John Deere site. Anybody know where the...
Ok so today I got back to testing the DCV coming out of the voltage regulator red wire that charges the battery… it was all over the place. I couldn’t get a constant reading. What does that mean?
Thank you! I will definitely replace the VR…I’m hoping it’s under covered under warranty by JD since the mower is only 1.5 yrs old and I have a 2 yr warranty. I will try and get the exploded view of the charging system and see if I can locate the ground wire. If you happen to have a link please...
Yes I was using the PTO since those 1.5 hrs were spent cutting the lawn. I’d be willing to test continuity but really need to see a how-to instructional video. I’m a noob with the multimeter and accessing these things isn’t easy for me to just dive in. The problem is there are very few...
I just read in the Briggs & Stratton alternator/charging manual I found online that “there is NO bench test for the voltage regulator.” I find that hard to believe so I am checking with the forum experts…is this true?
P.S. I would check the ground strap as you recommended but don’t know where to look for that. Please advise and I will check it.
the VR on this model JD is bolted directly to a metal shroud that is bolted to engine body…it’s not bolted to dipstick tube
Ok here’s the results of your prescription.
1. Checked stator Voltage first. THIS TESTED AT 47 AC VOLTS.
2. Checked DC Voltage BACK to the battery. THIS TEST SHOWED 12.2V. Then turned motor ON at FULL throttle. THIS TEST SHOWED 12.13V.
3. Then checked Voltage Regulator ground.
Check VR for...
Thanks Bertsmobile. i will conduct the check list on Saturday…sorry to ask dumb questions but just confirming that my MM should be on “AC” and use red test lead to test the yellow wire coming down from stator…correct? And switch to “DC”and use the red test lead when testing the red wire...
1-season-old JD ZTRak with a Briggs 25 horse. I removed the battery over the winter and stored it in the basement. (I never recharged it but have come to learn a trickle charge was needed so I have since purchased one.) So this spring I placed factory battery back into service and it fired right...
