Thanks to all who responded to the earlier posts regarding glow plugs.
I took the system apart again and changed the rail connectors to the right places--basically about the opposite of the way I had them installed prior. However, the problem still exists: Upon turning on the ignition switch, the glow plug light stays on too long, and the connector rails glow red.
Is there any possibility that the switch from Beru to Bosch plugs, which appear to be approximately 1-2 mm longer, could have any bearing on this, i.e., contacting something inside the chamber causing a short? I did not ream the chambers prior to the installation of the new plugs, because I do not know how to do this and do not have the proper "reamer" tool for this.
Again, I will appreciate any input on this latest theory.
