Whatever he did, it's working exactly as it should.
Did you ask him?

But, he charged the batteries
And, further, that the light was only on for a second suggests that the timer was not happy
Im judging it by the glow time on my 12v 1HZ 6 cyl engine. Even a cold start in summer has the glowlight on as long as yours. In our winter at 7c the light is on for 3-4 seconds.
Im still running 1995 glow plugs with 280k klms
I glow way longer than that with my manual glow. It was the having to cycle a few times on the key that lead me to dislike the super glow and go manual.
Also as for crank speeds I also found oil plays a large part. If I have 15w40 in (which is the oil I use all summer) and I try to start in 0 C or colder, even up to -10 C the oil is too thick and it cranks slowly.
When I was using my cruiser in -10 C and colder for winter use I ran 0W40 Rotella Synth. It made it crank properly.
But I would consider a 5W30 also for cooler temps. Oil makes a difference.
The figure you need is the voltage when its cranking. Even a dying battery can hold a 12v float. You can buy a battery load tester cheap that will simulate a load being placed on the battery.

It's worth measuring power at the starter too. We have a 12v HZJ75 on the farm that was having trouble starting from time to time. Battery voltage when cranking was okay but it was dropping over 2 volts across the starter motor solenoid contacts and about a volt through the battery leads. A new starter motor and some cleaned leads and it cranks like never before.
From memory it was getting as little as 6.4 volts at the starter motor.
The truck draws 25.42V when not running from positive terminal to glow plug head. When running, it draws 32-34V. Harder to start today. Temps cooler.
Still sound like a ground issue?
