[TR] heater hookup

[Paul Dorsey]

Thanks Dave and Bob!

The switch I have is one I got from my thrift store, but it works good. 
It's a headlight switch and has a terminal for headlights, taillights, 
dashlights and panel lights and ground.  It pulls out in two-stages just 
like a regular headlight switch and has a 30 amp fuse.

Maybe you've seen one similar.  I could proably hook something more 
important to it, but since it was free and looks fine, I'll stay with it.  I 
hooked up a connectivity meter to it (which I barely know how to interpret) 
and it shows full-connectivity when pulled out fully (between two terminals) 
but then, between a different terminal it reads where the meter's numbers 
'keep jumpin' making me think it might replace the traditional rheostat. 
Until needed though, I'll just run the heater off/on with the first two 
terminals since this switch fits fine.  (Proably this em-80's basic switch 
could replace half our 50's-60's console!)

I see no reason to upgrade.

Thanks, Paul Dorsey

ORIGINAL MESSAGE:
I need to hook up the wires on my heater.  I think there are only two- (is
this right?)  I cut the terminals heads off them and I forgot which wire 
goes
to the battery  (I am still positive ground).  I'm not much of a beter- but, 
I
bet it doesn't make much of a difference!
    I also lost the control switch.  But, I think I've got something to use 
as
a replacement.  It is a one-speed heater isin't it?

ANSWERS:
The motor is wound so it is not ground specific.
The original switch is a rheostat to allow you to run the heater in slow 
speed
or slower!
The motor and 4 bladed fan does not push that much air, maybe enough to heat
one side of the car and when the heater doors closed demist the windshield.
The 4 heater is much better for both applications.

Yes.  And no.  There are only two wires but the control is a rheostat so you 
can vary the speed by turnign the rheostat.  It is a 1.5 ohm rheostat which 
is different than the panel light dimmer which is a 3 ohm model (at least 
the the one on my car is.  YMMV)
