Help with your Balmar regulator
If we ask you for info about your regulator in your Revel (1st Generation Revels with RoamRig power systems, or 2nd and 3rd Generation Revels with external regulator conversions) here's a short video about how to find the regulator and see what's happening with it.
Note: for 3rd Generation Revels, the regulator is located in the house battery compartment in the back of the van.
- "BAL": This is short for Balmar, looks like 8AL
- "614" or "618": this is the designation of the model of the Regulator. MC614 or MC618.
- "LFP" or "CFG": this is the program type that you are on. 614 will show LFP, 618 will show CFG.
- "B-x" or "F-x" (where x is any integer 0-9): This is the field limit. 614 will show B-x, 618 will show F-x
- "- x -" (where x is r, b, a, or f): This tells you where the regulator is ramping (r), in bulk (b), absorb (a), or float (f)
- "bv" (looks like bu): This is the battery voltage measured by pin 9. It will be followed by a number such as 13.6
- "cv" (looks like cu): This is the "calculated" (target) voltage that the regulator is trying to achieve by varying alternator output. It will be followed by a number such as 13.6
- "b1": This is battery temperature. It will be followed by "nc" for no connection if there is no battery temperature measured or a number with c for celsius.
- "AL": This is alternator temperature. It should ALWAYS be followed by a number with c for celsius. If it says "nc" afterward, you have a major issue and should NOT run the alternator.
- "b2": This is battery temperature. It will be always followed by "nc" for no connection as there is no second battery temperature sensor ever used.
If the regulator screen does not turn on when the engine is running, then you can use a multimeter to find out if the regulator is getting power. Here's a quick video of which wires to check and how:
