Eastern Standard Time, LISTSERV@GERRY.VANAGON.COM writes: The throttle valve switch has failed on my 85 Westy. This switch is located under the throttle rather than above the throttle body as shown in the Bentley Manual. There are no switches on top of my throttle. The part number is 025 906 017. This number is on the plastic plate that holds the actual switch. The actual switch has the following: Hartmann Serie 506 4A 250V~. The switch is open all the time, so I am unable to know whether it should be NO or NC. There is a little cam on the throttle shaft with two bumps, one that is supposed to actuate the switch at idle and another that actuates the switch at full throttle. If anyone knows where I can get a good replacement switch I would be glad. Alternatively, I can get a new microswitch and adapt it to the existing holder. If anyone would care to give me an opinion as to whether it is a NO or NC switch I would like to hear from you. I know the 84 switches on top are NO.
Ron, those switches are not available unless you can find a good used one. It can usually be repaired. Are you sure it is not working is the first question ? If not then you can gently remove the cover with the use of a sharp utility knife blade. Go easy so as not to break the cover. Once open it will become obvious what is wrong and you should be able to clean the corrosion from the contacts, spring plate and push pin actuator and get the switch back operating. Sometimes that plastic push pin seal has become swollen and will not allow the pin to move freely, cleaning and light lube may work or discarding that seal and covering the area with Dielectric grease may work also. The judicious use of Dielectric grease on the switch parts is also beneficial after you have the corrosion cleaned off. Be sure to fully understand the location of the spring and switch plate before they jump out of place and your left wondering how they go back. That little spring is always wanting to get lost so be careful and working on a big white fluffy towel and the use of a pair of fine point tweezers are advantageous. After your sure the switch is functional you can replace that cover you removed with some plastic glue or Crazy Glue. After you have the switch back together and operational you need to adjust the switch plate so that the switch closes (switch is NO - Normally Open) as soon as the throttle plate starts to move and then opens again at full throttle plate opening. If you cannot achieve this in the normal movement of the switch plate this is due to the plastic cam being worn. The remedy is to bend that metal arm of the switch until you can get the switch to contact the plastic cam and operate the switch within the correct parameters.
