What is it? (Redundant 3-Step and a ?)

Postby Angus on Tue Nov 04, 2014 8:15 pm

Hi All,

I have a mystery box hooked up to a dual Regulator setup and
I'm hoping someone can ID it before I tinker with the system
for a battery upgrade and shaft generation project (also using
an Ample 3-Step and alternator).

Other onboard Ample products include an EMONII and a 1018
labeled battery sense. Single Ample alternator on a perkins 4108.

The 2 regulators have a manual switch to select between them which
diverts field and battery sense (DPCO). None of the boxes have model
numbers front or back but I'm pretty sure the regulators are
3-Steps because the circuit board layout is identical (but larger than)
my purchased 1021A.

Thanks!

First pic is the top of the board showing the 2 regulators:

This is the bottom of the board showing the switch and mystery box (on the right):

Here's a closeup of the terminals and wires for this mystery unit:

The mystery unit is an old Alternator Current Sensor to send a signal compatible with the Emon input.

Its all from the late 1980s.

Thanks!

It's a tribute to Ample products that this stuff still runs fine.

There are many such systems still working - long after computers of that era are all in landfills.
