Heater coil relay 12V
Paruzzi number : 70685 Original VW number : 443911261
Useful information from Paruzzi magazine and from our YouTube channel :
testing the coil You can easily check if the electrical voltage in the primary circuit of the coil is correct by using a multimeter. High voltage measurement at the secondary circuit cannot be performed with a standard multimeter.
(dis)assembly of the spark plugs It seems like a simple job, replacing or checking the spark plugs of your VW. Yet we see that it is not always done according to the rules. Spark plugs that are not properly assembled or have been disassembled carelessly can cause a lot of problems with the engine.
finding the top dead center What does Top Dead Center (TDC) actually mean? If you study the theory of the operation of an internal combustion engine - or the "petrol engine" - it will become clear. Without going into too much detail about the theory, we have to talk about the otto cycle, better known as the four stroke cycle.
Engine overhaul - video 04 removing the distributor drive shaft We want to give extra attention in this video to the position of the distributor drive shaft of the VW Type 1 engines, . If the drive shaft of the distributor is not correctly mounted during the engine overhaul, problems can arise later with the adjustment of the ignition timing. Disassembling the drive shaft is then the only solution.
measuring electric current To measure current, you must interrupt the circuit through which the current flows. The ammeter must be connected in series. Therefore, that a current clamp is a better solution. This type of ammeter does not affect the circuit to be measured, it measures the magnetic field around the conductor (induction principle, see edition 26).
ignition timing - dynamic In this edition, we will adjust the ignition with the engine running, this is called a dynamic measurement. VW advises in its workshop manuals this way of adjusting all air-cooled VWs from August 1970 onwards. The static adjustment with a test bulb is then only suitable for a temporary engine adjustment on these young Volkswagens.
Engine overhaul - video 12 the flywheel In this video, we'll explain how to disassemble and assemble the flywheel, and what tools you'll need to do so. To disassemble the flywheel, you will need to unscrew the gland nut. This nut is attached with a torque of 350 Nm, it will require some force to loosen.
spark plug heat range The construction of the part of the spark plug that is screwed into the cylinder head determines the degree of heat. The spark plugs are screwed into the cylinder head, which is the warmest spot of the engine. Temperatures can be as high as 1000°C. The electrode part of the spark plug extends into the combustion chamber of the cylinder head.
testing the condenser Without the condenser, the ignition will really not work properly and the contacts will burn in quickly. So it is important to measure at regular intervals if the condenser in your VW motor is still working.
checking the Dwell angle There are several devices available to dynamically measure the Dwell Angle. These are usually combined devices that measure battery voltage, Dwell Angle and advance. Others can also be used to measure the CO content of exhaust gases.
