big-phil Posted October 1, 2008 Author Share Posted October 1, 2008 Last I saw you, I thought you lost that a long time ago. LOLDo you have a power filter on the MSD power wire? yes Quote Link to comment Share on other sites More sharing options...
AK-Z Posted October 1, 2008 Share Posted October 1, 2008 I would take a multi meter to a injector connection just to be sure. Quote Link to comment Share on other sites More sharing options...
big-phil Posted October 1, 2008 Author Share Posted October 1, 2008 check this out I found a connection that came unsolderd. this is what that is Metal Oxide Varistor (MOV) The MegaSquirt-II PCB receives electrical current along from the vehicle's battery. If the voltage from the charging system surges or spikes (rises above the accepted level) the Metal Oxide Varistor (MOV) diverts just enough current into the outlet's grounding wire to keep the voltage supply to the components at the acceptable level. A MOV forms a connection between the hot power line and the grounding line. A MOV has three parts: a piece of metal oxide material in the middle, joined to the power and grounding line by two semiconductors. These semiconductors have a variable resistance that is dependent on voltage. When voltage is below a certain level, the electrons in the semiconductors flow in such a way as to create a very high resistance. When the voltage exceeds that level, the electrons behave differently, creating a much lower resistance to ground. When the voltage is correct, an MOV does nothing. When voltage is too high, an MOV can conduct 'excess' current to ground in order to eliminate the extra voltage. Because the extra current is diverted into the MOV and to ground, the voltage in the PCB power supply line returns to a normal level, so the MOV's 'by-pass' resistance shoots up again. In this way, the MOV only diverts the surge current, while allowing the standard current to continue powering the components on the PCB. I've had voltage spikes and drops, and this has got to be it! I'll put it back together and report back. Quote Link to comment Share on other sites More sharing options...
jeffer949 Posted October 1, 2008 Share Posted October 1, 2008 Thats been my problem also. Ill check it out. Voltage spikes make my ecu reset and ya. not a smooth running car Quote Link to comment Share on other sites More sharing options...
jeffer949 Posted October 1, 2008 Share Posted October 1, 2008 well that wasnt my problem Better luck to you phil. Also did you read if they can go bad or not? Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted October 1, 2008 Share Posted October 1, 2008 Phil: You may want to consider getting one of the p&h boxes that are being made now - let your low imp injectors really work! http://jbperf.com/p&h_board/index.html I have some of the original board for when I finally get my system installed...

BLOZ UP Posted October 5, 2008 Share Posted October 5, 2008 Another sign of flyback failure: Your MS catches on fire. Don't ask how I know. Quote Link to comment Share on other sites More sharing options...
