This section is written as an aid for troubleshooting the Flow Meter for electronic technicians only. It must not be used by service personnel with no training or knowledge of electronics.Removal And Replacement Of Components
Remove the silicone rubber sealant by cutting the rubber away from the part. Cut the connecting wires of the component and remove the component from the circuit board. Use a 25-75 watt soldering iron with a clean .12" (3,0) tinned tip and remove the remainder of the wires, one at a time. This can be done on the foil side of the board. Use either Dri-Wick and the iron or drill through the solder from the component side of the board with a fine drill.
Too much heat causes separation of the foil. Remove the remainder of the varnish from the foil with a knife. Install the new part with .03" (0,8) rosin core solder of 60/40 or 63/37 alloy. Do not use acid core solder.
IMPORTANT: Never install a removed part; at all times, install new components.Clean the solder with alcohol or trichlorethylene. Make a check of the circuit to be sure that it is in operating condition. Paint the areas where the varnish was removed.IMPORTANT: Installation of components by methods other than the directions above can cause damage to the circuit board.Basic Electronic Troubleshooting
More than half of the circuit problems are caused by failure of the batteries, the unit that holds the batteries and the meter movement. Up to 90% of all circuit problems can be found by inspection, ohmmeter and voltmeter checks, the wet finger method and the probable cause chart shown below.Voltmeter Test
The voltages listed below are the results of readings taken between the test points and the ground foil or the negative side of the battery. To get similar voltmeter indications, a meter of 20,000 or more ohms per volt must be used. All voltages are 10% except where specified. All test points with an (A) after the number are for the flow meter and those with a (B) after the number are for the tachometer. When taking voltmeter tests,
