john in KY Posted August 30, 2009 Share Posted August 30, 2009 The entire bracket has to be grounded for the part in question to work. No grounded bracket=no spark. Link to comment Share on other sites More sharing options...

GeneralDisorder Posted August 30, 2009 Share Posted August 30, 2009 That is the ignition amplifier - it is used to trigger the coil from the ECU signal. They are known to occasionally fail, but it's not common. GD Link to comment Share on other sites More sharing options...
King of Poop Posted August 30, 2009 Author Share Posted August 30, 2009 (edited) ok...I'm getting .6 volts out of the resistor or ignition amp to the coil...that doesn't sound right to me. what should I check next?

GeneralDisorder Posted August 30, 2009 Share Posted August 30, 2009 With the amp connected and powered you should have 12v to the coil + side with the ignition ON. If you don't then you have a bad ground or a bad amp. GD Link to comment Share on other sites More sharing options...

King of Poop Posted September 8, 2009 Author Share Posted September 8, 2009 anyone know where I can find this part...besides a junk yard? Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 9, 2009 Share Posted September 9, 2009 Dealership or junk yard as far as I know. They are very plentiful in the JY's and rarely fail. GD Link to comment Share on other sites More sharing options...
naru Posted September 10, 2009 Share Posted September 10, 2009 (edited) anyone know where I can find this part...besides a junk yard? You don`t need one.A bad ignition amp won`t prevent you from having 12V on at least one side of the coil.Check fuses,fusible links and the ignition switch instead. BTW-the ignition amp doesn`t power the coil,it grounds the coil. Edited September 10, 2009 by naru Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 10, 2009 Share Posted September 10, 2009 Hhmmm - yes were you checking power at the round plug or the two-pin spade terminal to the amp? If you don't have power at the black/white wire on the round plug with the ignition ON then you have a supply issue. I may have mis-understood what you were refering to when you said you had 12v to the amp as both the round plug and the two-pin spade connect to the amp but only the wires from the round plug connect to the coil....

akc Posted September 10, 2009 Share Posted September 10, 2009 I will reiterate the fusable links in my car they regularly come undone and have to be pushed down. they can do weriod things to a car. Mine does not get enough gas to the carb when they are not in all the way and then the shift up light comes on. 86 My nephews car he got free because they could not figure out what was wrong with it it would not start at all. (81 sub) All that was wrong was the fusable links needs to be pushed in as they popped up a little. his did absolutly nothing other then click when he turned the key in the ignition. (it is not a perfect car though it runs on only 3 cylinders) little black box by the overflow tank pop off the top and pull them out then push then down all the way. mine loose conection about 1 time every a month or so. However it usually is just one fusable link. HOWEVER I AM NOT A MECHANIC. But we spend a week trying to figure out what was wrong with ours. and $200 in unneeded parts. We even had our mechanic friend stumped and he is really good most of the time. Link to comment Share on other sites More sharing options...
