1970 TRANSDUCER ADJUSTMENT

[john chalk]

ok I have sourced a 1970 transducer for my 64 climate control. told it would work.

it does but I need to adujust it and  unlike the 64 transducer that had the screw

adjustment at the bottom this one appears to have none.   at 65 degrees its getting

8.6 volts but still holding 7 inches of vacuum - still too much for the power servo arm

to move far enough forward to actuate the mode control so the AC comes on.

any ideas how to adjust

cheers

thanks David.  I actually reparied the old one - did not think I could but the 64 transducers are not that complicated - refitted and it works as well.

Thanks for the replies. here is an update.  the 64 transducer I got had the ports around the wrong way to I mounted it above the vaccum lines behind the glovebox successfully and ran an earth wire to the chassis.  This transducer did not seem to work properly thus I got the 1970 one. I sat it on the glove box door with the same earth lead and the same issue seems to have been happening. so after so thinking I checked the continuity of the earth. 4 ohms. !! new earth and the 1970 transducer works jsut right. 4 inches of vaccum at 65 degrees and 14 inches at 85. all good.
