Does anyone have a simple digram that shows how/where the tension wire from the jockey pulley on the base of the series 2 heater travels to? Looking at it I can't tell whether it means to have more than one wire or why it has two wheels etc. Can see it has been repaired in the past.

The Hayes book doesn't show it but talks bout it. I follow how I can attach the wire to the rear/second wheel but how I string the wire around the double-wheeled at the front? Once? Twice, Cris-Cros.? Any thoughts?

 

I wonder if your system predates mine. Every picture I have relates to rods moving flaps with not a pulley in sight.
I'm sorry, but I don't think I can help with this one.

All the forum posts and Google images of the air bender suggest it is a more primitive model as it only has a single flap door at top and has this strange pulley linked to the flap control. Latter models seem to have a complex box of rods and an amplifier instead.

 

Gary Crosby at Jag-Aire might be able to help.

Gary was indeed very helpful and had not come across this unusual model before but dug out some spec diagrams for the beast. As I continue to try and piece it together I realise the short comings of my education in pulley physics.
I have used wire fishing line and crimps of 0.7mm to match the original wire. PROBLEM I have now is figuring the 'set' position of some of the internal flaps of the heater. (see pictures) I am not sure (a) if the wire original wire had a spring at either end or just one at the left as in the diagram, and (b) whether the armature is in closed or open position when the pulley tension in pulled left or right (or knob position at top or bottom). This armature effects the lower flap near the floor of the unit but I cannot figure whether having the FLAP CLOSED stops HOT AIR traveling into the cab of the car OR whether having the FLAP OPEN dilutes the hot air with a cold intake to reduce heat. I can imagine it could be doing either. The knob set to top is HOT and set to bottom is VENT.
