low charge voltage at startup

83 300sd.

Ok, so I've been working on getting my charging system up to snuff. I have found 3 little issues that I have cleared up.

I messed up the wiring when I installed an aftermarket fuse block for the climate control. That has been corrected. 8 volts inital charging up to 11 volts

I pulled the fuse from the bass amp and electric remote entry.
11 volts up to 11.5.

So now , after I start the car, I am still only getting 11.5 volts at idle until I get going. After I drive a few miles, I check again...13.8 to 14.1 at idle.

My only thought is that my glow plugs were upgraded to the stay on for 30 seconds to a minute regardless of whether the engine is running or not.

How would you check that? Any other ideas?


PS. With the car off, recconect the battery. Car takes .58 amps for 5 seconds...then drops and stays at .13 amps. I assumed thats my aftermarket radio sleep booting.
