The alternator manufacturer did a nice job with the regulator design. Whose is it?

This was Hitachi. I expect the same performance from IR Denso designs as we've done similar, though less severe testing with those in the past.

As of yesterday, Barry had one new proto board loaded and was working on the second. Takes a while by hand.

Default Working!

The first 2nd prototype board is now running. We're very happy with that and will start running all the tests over again to verify performance and operation.

Have both CPI2 boards loaded now and should be talking to each other tomorrow.

Spent some time on software to detect if either of 2 coil pack fuses are blown and makes the check light come on.
This won't allow backup battery to send power to bad coil pack so this way the backup battery will still run the good coil pack if required.

Successful testing of the dual boards together will finally allow us to freeze the design and order production PCBs. We'll continue testing while those are in process.

Dual boards up and running early this morning. A few more software issues to solve yet as was expected.

Any updates? My brand new in the box CPI firewall forward is awaiting its new CPI 2 controller and backup battery.
