Another possibility is the notice that came in the mail a week or two
ago from Garmin offering a trade-in program for all GX series owners.
They will give you $2000 for your GX65. Unfortunately, like most of
these offers, you can probably do much better on the CNX80 price than
the full list $11,995 that Garmin bases the deal on.
Here are the numbers:
CNX80 $11,995
GX55 $1500 credit
GX65 $2000 credit
GX50 $2500 credit
GX60 $3000 credit
"Limited offer ends soon" - they don't say when "soon" is though.

I posted this the other day and got no replies so I will try
again...............
I have wired up the VANS supplied internally regulated ND alternator as
described in Z-24.
If I put the master to the position that would bring the alternator online
if the engine was running, the 5Amp OV breaker pops. Is it reasonable for
the field windings to draw more than 5 Amps when the altenator is not
turning? (The OV Protection module is not the culprit since if I pull the
plug for the excitation out of the altrernator, no problem.)
Thanks Steve.

Fellow tron listers,
I am installing my backup alternator (SB20) on the vacuum pump pad on my Lalonde-built
O360.
The best I can figure is that the alternator output stud's best position is at
4 O'clock when looking at the back of the engine. Also, with the pad provided
- it seems to stick out quite a bit to the rear of the engine.
I have taken photos if anyone needs additional explanation.....
I sure do......Is this what everyone else with this setup has ended up with?
Thanks,
Ralph Capen

Steve,
About a month ago we experienced a similar situation with a Van's
internally regulated alternator for an RV-4 I was helping with. It
"felt like" a short in the wiring but it wasn't; the alternator's
control terminal measured very low resistance (<2 ohms) to ground.
A call to Van's very savvy customer support electrical guy (Ben)
confirmed a bad alternator and Van's quickly got another one on its way
to us. The new one doesn't trip the breaker.

I note the idea of substituting welding cable as more flexible than its
sister size in AWG - however, have you heard of the flexible cable the
numbnutters are putting in their souped-up Civics for kilowatt FM amps?
Locally here, the car stereo stores are stocking #00 and #4 cable in
clear flexible insulation - which I am told meets transport specs for fire
(?) I have checked it and it certainly seems to meet flex needs.
Cheer, ferg

Unless one were to use a conduit for this automotive cable, the insulation is not
likely to pass a DAR inspection.
John Rourke did some testing of Tefzel, auto, and welding cable. Here is a partial
quote from this Feb 22, 2002 post:
"I also, once upon a time, compared automotive battery cable to welding
cable and Tefzel (22759-xx) in a 700+ degree solder pot and also with
flame tests; the automotive cable burned immediately, made thick oily
smoke and sustained a flame after the source was removed; the Tefzel
smelled fairly nasty but would not burn right away (and would not
sustain a flame at all); the welding cable gave off kind of a "hot
rubbery smell" which wasn't irritationg at all, and would not burn or
melt, but did swell just a bit."
Until someone does some testing of this auto sound cable which establishes that
it can withstand heat and abrasion, we should avoid this stuff.
Fergus, while searching the archives on this topic, your post about weighing welding
cable came up. Something like 55 grams per foot for #4. Did you weigh
the clear insulated auto cable by any chance? I'm curious why you brought this
wire to our attention and am looking for some possible advantage.
Jim Foerster, J400, wiring.
