MEP-002A Battery Charginig System Troubleshoot

[catman393]

Hello All,

I'm trying to verify that I have properly troubleshot my DC Charging System.

My measurements are:
Resistance Between Stator Leads (disconnected) - 0.9 Ω
Left hand lead to ground - OPEN
Right hand lead to ground - OPEN
Stator disconnected and engine running - 43.2 VAC
DC Voltage regulator red banded wire - 25.97 VDC
Batteries - 25.99VDC (13.14 VDC & 12.86VDC)
Stator connected and engine running - 2.215 VAC.

From the various threads on here and Smokstak I've read regarding this issue it's either a bad stator (yuck) or a bad DC VR ($$).

Can someone confirm one way or another? Are there any other reading at TB-6 I can take to verify/narrow it down?

At one point I'm fairly certain the charging system did work but I can't 100% confirm that.

Thank you all in advance.

Check out the sticky 002a or 003a DC charging system test. Sounds like the regulator is bad. If you need one, TripleJim who is a member sells newer versions that far exceed stock. http://www.lakeserv.net/mep/index.html

I installed one of triplejims regulators on one of my 003a during an ice storm last winter. easy easy install perfect fit and perfect function. I liked it so much i got more and just replaced the originals on my other gens as a precautionary measure. the triplejim regulator doesn't boil my battery as much either.
