Don't mean to hijack a thread. But I'm having a simular problem. With my half ton conversion. For all I know my voltage reg could be bad in the ecm. When I hook it the wires up my it will not charge at all. I tried the external regulator. It over charges the battery juicing 18v wile driving. My question is. The small wires to the regulator. One of the 2 should be hot with the key on correct? Thanks guys

No I haven't got any kind of crank sensor or rpm signal to the ecm. I haven't messed with any of the tach or rpm yet. I wasnt sure if the 12v setup would communicate with the gasser ecm stuff. I have all gauges working except the rpm and temperature.

Must have tach signal to charge!

Thanks mysterync did not know that. Any idea how to make a gasser ecm read the 12v tach. Is it possible. Thanks a lot for the info
Is it an auto or manual? Sent from my SCH-I605 using Tapatalk 2 |
The 12v is manual the 1/2ton was auto

Well I ended up putting an external regulator on and the system is charging now but it is over charging the system. Now its at 18v at an idle. Any suggestions?
---AutoMerged DoublePost--- The tach is working perfectly fine the only problem I have is the volt meter is only reading about 12v and my check engine light is on saying that my volts are to low on my charging system. So I ended up putting an external regulator on and the system is charging now but it is over charging the system. Now its at 18v at an idle. Any suggestions? |
