Golf Driver mk2,throttle body heater tes - Tony Soprano

I have contacted a carburettor specialist,who has informed me that a likely culprit for the carb icing I suffer from on the Pierburg 2E2 carb in winter weather,could be the throttle body heater.Does this sound possible?If so,how do I get to the thing,and whats the best way to test it?Any help much appreciated,
Tony

Hi Tony,

These devices are usually in the base of the inlet manifold just under the carb.

To test, take your choice of the following:

1) Connect an ammeter in line with the wire that goes to the heater. When running, it should draw some meaningful current which will drop as it heats up.

2) Disconnect the feed wire to the heater. Using an ohmeter, check the resistance between the wire to the heater, and earth. A failed heater will have a very high, or infinite resistance. I don't know what the specs are, but I would be surprised if a good heater has a resistance of over 100 ohms at ambient temperatures - when they get hot, the resistance increases.

3) The direct method! Take the heater out, wire it up, and see if it gets hot!

Does the car have the provision to draw in warmer air in winter from near the exhaust? These are sometimes controlled by a vacuum controlled "thermac" valve. The vac pipes and/or valve can fail and cause icing.
