Posted November 28, 20177 yr I talked to a "really good" mechanic recommended on the phone He said to check my "power-up relay" and my "ECM relay" in my fuse box I cant find anything called a power up or ECM relay on my '99 CTD Are these two relay something that dont even exist ?
November 28, 20177 yr We do not have a power up relay. We use an ASD relay. That may be what he was talking about.
December 8, 20177 yr ASD relay was what was bad on my truck causing it not to charge. I thought it was the PCM because the PCM controls charging /w an internal voltage regulator.
