Later they developed their own digital System-P with a 35 pin conector. More tips will be added as I remember or other members add their experiences. After that it will look the way it is on the photo 10. Air sensor plate- Balance beam activated by incoming air to the intake manifold. Otherwise you just turn form step 1 to step 14 and watch the lights. Fuel distributor- Control center, contains a regulator to keep system pressure constant. Use a beam caliper and measure how deep the guide bar is getting inside in comparison with the regulator body.
I have cut an M3. The small spring used in this device is from a set of brake block attachments. The fittings supplied adapt to the banjo and banjo bolt with copper washer gaskets. Alternately, clean the dispenser halves in an ultrasonic bath about 15 minutes for each of both of them. The main moving part is a central pin which is controlled by the air sensor plate. D-Jetronic is really very reliable and I am always surprised how reliable a more than 40 years old electronic can be.
Do not rely a workshop's competence just because of the presence of such a tester. Opening the valve to allow flow exposes the gauge to control pressure. The bits of the system include the fuel pump, pre-pump on some models, fuel filter, accumulator, fuel distributor, warm-up regulator, injectors, auxiliary air valve, air sensor plate, cold start valve, thermo-time sensor and on newer models an oxygen sensor, frequency valve and mixture control unit were added. Despite of its size and weight it is meant ot be used in cars. The gauge should read about 15 at this point. Be sure to check that.
Measure it with a beam caliper but be sure not to squeeze the spring with it. The correct mixture setting will be when the duty cycle is about 50%, this means that the time that the voltage is low will be about the same as when it's high. This will let you get even lower pressure when then engine is cool and will help you to start the engine more quickly during winter time. Detach the operational fuel pipes from the metering unit and from the fuel distributor that leads the fuel towards nozzles from the metering unit side. The cold start valve will still spray and you will likely fire up for a second or two and then die. I recommend it as a tester manual. On the photo 8 you can see the element resistance level that is equal to 26 ohm.
Starts hard cold- This is almost always the warm up regulator. Up to 3,500 blows per minute. Always follow all of the instructions and warnings included with our products. If you have an O2 sensor unplug it. Using the pressure tester on the 83 turbo is much easier.
I read injector timing from my 4 channel oscilloscope. If you need to return or exchange an item you can send it back at no cost or take it to your neighborhood store. Assembling fuel dispenser-distributor Be sure to be holding the sealing gum paste spool in the upper half of the dispenser. If the check valve won't hold rest pressure you will have a heck of a time getting going again after the car sits for 5 minutes. After that be sure to start cleaning thoroughly and blow dry the remaining water with compressed air.
Harbor Freight Tools stocks over 7,000 items in categories including automotive, air and power tools, shop equipment and hand tools. When warm the Bimetal is loose from the spring anyway so this adjusttment does nothing to the control pressure when the engine is warm. Screw the fuel validation check dispenser as indicated above. There is a dense grid under the big connection hose photo 16. Motorsport and performance units also available. Turn switch postions X and Y were however foreseen for that. To implement this feature I removed the original guide bar from the body.
I need a long, dark and cold winter for that, allowing me to work only on this. Look for items sold by Walmart. As I have partially not yet verified what exactly it measures, I quote Brad's info in italic. And on the other hand I have to try all my testers now and repair them if necessary. You do no thave to insert multimeter tips form pin to pin, you can do it easily via turning switches. After clearing the regulator you can try to blow into these holes before installing the plate.
