I think you should look in the spec to see which one fits a particular type. If
it still does not fit, try to consult with some company.

Hi Group No joy with Actuonix. I have 2 burned up indicators and the internal potentiometer
wires going into unit melted. I urged them to bench test an actuator
with an indicator from same batch sent me. They finally got back to me and
said that their test works fine. They asked I ship back and they will repair
under warranty if it's defective. The actuator is working fine, I think if I
sent stuff back it's going to be a long drawn out battle with no joy in end. I
purchased a Ray Allen RP4 Indicator and POS 12 Position Sender. More work because
had to install additional sender. That said Ray Allen components very high
quality and amazing as it seems works perfectly! Ron P.

???? as shown in the z-drawings, brownout boosters are
switched to support ONLY the e-bus . . . just milliseconds
before the starter contactors close . . . and for as long
as the starter button is held closed. The "normal feed"
path includes the requisite diode.

33 volts? No . . . only 14v. We're keeping the
e-bus supported at 14 volts for the cranking
interval that the battery is below 11 volts.
