Converting a 005A with a Digital Controller

good afternoon i have one of these generators I want to convert mine also do you have a detailed part list

contact Larry @Cowhunter
he bought all the parts and can tell you exactly what he got and where he got it

@Cowhunter what did you use for the backup battery?

 

[peapvp]

@Scoobyshep we havent installed a backup battery yet.

The MeBay documentation does not specify a particular Battery or a even a voltage.
What is also important is that the Plus terminal off this back up battery is grounded to chassis and the negative terminal connects to E3 on Mebay Controller!

There is a Parameter # 28 in Group 1 listed for Auto start operation, in case of mains failure for the D72 Version
I have absolutely no clue of what ABF is or what they are talking about in this parameter description

If you find any more information Scoobyshep please let us know.

Wow.

A positively grounded battery on a modern piece of electronics seems unusual to the point where I would be wondering about a documentation error. It would certainly have me being extremely careful. If you probe the (-) point when the controller is powered up is there a voltage?

I realize it is a long shot, but have you reached out to MeBay directly? They do, at least reportedly occasionally, respond, sometimes with useful information.

All the best,

@2Pbfeet
Yes, I agree. The back up battery has not been a priority for Larry. It affects only the Date and Time and therefor Maintenance schedules, which can be setup.

I checked several other MeBay Controllers and those have integrated 1.5 V Battery's as Backup or no backup at all.

We have not contacted MeBay as this has not been a priority.

@Scoobyshep and @2Pbfeet

when Larry and I started this project a few months ago, I thoroughly investigated this reversed battery polarity issue by checking several older D7x manuals and the controller itself without contacting MeBay.

The reversed polarity for this backup battery is consistent in all of their manuals, written and in wiring diagram.
All of their specs as to I/O’s checked out during test and implementation.
I would say that it is save to assume that this battery connection is reversed polarity for whatever illogical reason they did it this way.
