Hmmmm . . . I'm mystified as to why you were
experiencing poor finish on your crimps.

Here's a link to the manufacturer data sheet :

Wag Aero's products seems to be the T54C1 'Rectangle Panel Mount w/ 2

Most interesting. No wire, no connection, no nothing ;-)

| Subject: | Dual Battery Contactor |
Just came across a new (to me) product from Cole Hersee. This is a battery contatctor
with a dual battery voltage sensor and control module added on. From
the literature this appears to be a simple solution to automatic isolation and
control of a dual battery, single alternator electrical system.
Take a look at the lit. and comment. Upon first blush this appears to supplant
the dual contactor with a single contactor and a voltage sense and control circuit.

| Subject: | Switchology Question |
Guys: I have a newly finished Rocket, wired IAW Z13-8. My system has a big battery,
a 60 amp alternator (Plane Power) and an SD-8 backup. I have not tested
the SD-8 yet and was wondering if there is a protocol for that, that I should
observe.
I have a three position main DC Master switch (off, Batt, on) and no avionics master
(I prefer turning each on and off individually). I also have separate E-bus
Alt Feed and Aux Alternator on-off switches. I plan to test my SD-8 on the
ground with all my avionics off except my engine monitor (which has my volt
and ammeters) to see if it is wired correctly and shows Aux Alternator output.
Should I start on the main system, turn on the engine monitor, and then switch
the main to Batt, and then the E-bus on, and then the Aux Alt on, and then
the Batt off?
If that is all correct, then airborne if I lose or shut down the main alternator,
is the sequence the same? Haven't got the diagrams with me at the moment and
I'm trying to write a procedure. Any help would be appreciated.
Thanks,
Lee...

Thanks,
We are fortunate that electrical units started out metric and haven't changed a
bit. (Okay, there were Mhos, CPS and a few stragglers). Photometric units contain
plenty of traps for the unwary.
BTW: "Cree Achieves 186 Lumens per Watt from a High-Power LED
High-performance chip and R&D package combine for record-setting efficacy"
Amazing.

This looks very much like what Yandina (marine electronics) calls a combiner. I
have one on my 1976 GMC motor home. It is installed across the factory installed
isolator (diode). The difference that I see, is that the combiner we're using on
our motor homes works both directions (i.e. chassis -> house and house ->
chassis). What this means is that if we are on the road it charges the house
battery(s) and if we are docked with shore power (or the generator running), the
chassis battery will also be charged.
It works as advertised and I'm happy with it. I have the Cobiner 100 (good for
a
100 amp alternator). It lists at $79.95 and on sale for $59.95 which is what I
paid.
Regards,
Dennis

It appears to be a "smart" contactor that doesn't close
until the upstream system voltage exceeds 13.2 volts.
It appears also that you can force the contactor closed
for cranking assist.
I.e. just like a plain vanilla aux battery contactor with
an aux battery management module built in. You'd still
have a manually switched battery master contactor.

You can't hurt anything with by mis-positioning switches.
You won't see any output from the SD-8 without being
well above 2000 rpm. So you can craft any procedure that
makes sense to you.

Hi Bob,
You are correct, I am planning on using diodes. I have not looked at Z32 but I
believe long wires and small fuses make sense.
Thanks,
Rocky
