Re: Part Number and No Spark

modules???<br /><br />Are you talking about the Motor Cable Assembly or the Amplifier? Also I dont see a rotor on my diagram. <br /><br />Thanks

Re: Part Number and No Spark

Brief description before we begin. Points are the trigger mechanism in your system. They are dual points so the time period that the points are open are much less than that of a single point system. Both points are in parallel and are set according to your manual with one set of points opening before the other. The amplifier is used in this model to releave the points from carrying the amount of current of previous systems. To test the module we need to ground it to the block and make several clip lead connections. The first connection is from the points and that one lead can be disconnected to test the points and then can be used to trigger the amplifier to test that device. We will need to obtain 12VDC from the motor. If battery is connected to its normal hot side on the solenoid you can use this to clip the 12VDC lead on the amplifier direct to this connection and bypass the keyswitch which would normally supply the 12Vdc. The other lead you will use for test normally is connected to the coil. If this is easy to disconnect from the coil it is a good idea to connect it instead to a small bulb like a running light so you can see if the output of the amp is ok.. The tach lead is not used for this test and is the other lead besides the 12Vdc lead that went to the controls. Just put a piece of tape on it to keep it from touching ground. If you ground the module to its normal position you will eliminate a lot of ground connections required for the test. Here is the test. Connect the module up to ground as discussed, hide the tach lead, wire up the output that normally x-conn over to the coil and connect instead to the light bulb one lead, ground the other. Power the unit up on the 12Vdc lead and use the lead that went to the points to turn off and on the light. Remember the module normally is connected to the coil and current continues to flow until the points open and turn off the current......the field of the coil collapses and spark would occur. In the test as you touch the point lead to ground the light goes on. If I count them right you only are using ground and three leads for the test...Module then good or bad. End of step 1

Re: Part Number and No Spark

I did not answer your question about the distributor and rotor yet because you indicated everything was in pretty bad shape. If we get the amplifier going we will move on the the coil, distributor, rotor, hV wiring to the plugs, and make sure the points are set correctly and providing that very short dual point opening that this system provides. You can be the points in the test above by closing and occasionally opening the circuit into the module. My test after I read it sounds very complicated and it is not. It really could be described as an electronic simple relay with the points being the pushbutton (normally closed) and the relay which is normally providing 12Vdc opening up. This is the first crude electronic system and does not use capacitive discharge to power the coil. I guess thats why they called it an amplifier. Those of who work with electrical devices would say today that is a very non-linear amplifier. In fact it is the simplist type of all: It is either on or off..Why its digital. So tell every body you have a binary output solid state digital, one or zero, ignition. system.... Ha

Ok I got step one and will start on it tomorrow.<br /><br />Thanks,<br /><br />Ron

Re: Part Number and No Spark

Ron,<br /> <br />Ok I finished rewiring the harness and several parts on the motor, Ok so tomoroow I will do the test. Ok here is a problem Both Amplifiers wires were corroded up to the housing so I melted some of the wax on the back side down tell I got to good wire. I dont know if either one works though. I did find out tonight that the starter is good but the silonoid is bad. Touch back with you tomorrow..<br /> <br />Thanks,<br /> <br /> <br />Leon
