NS2 question

[armas west]

I replaced my NSR in 2009 with an NS2. It seems to have worked well. Last week the charging system stopped working. I have a 125 amp Amptech alternator connected to 4- 6 volt batteries, in sets of 2 in parallel. There is a temperature sensor on one battery post.
I pulled the alternator and had it checked. It is fine. The NS2 shows a steady green light on the Status LED. No red lights are on. One 2 battery set checked out 12.24 volts. The other bank 11.4. this while still connected in parallel. A hydrometer check showed one bank "green" or charged, and the other "red" or seriously discharged. I am taking the one set of batteries to my supplier Monday to check out.... In the meantime, what does the steady non-blinking green status led tell me? The trouble shooting guide talks about a flashing green light. The light was on whether the ignition key was on or off and when the motor was briefly started up.

Suggestions?

The green LED should be flashing, not on steady. Try removing all power from the unit for a few seconds to see if that clears up the problem.
