Tach delay for a few seconds after starting the car.
I noticed the other day, when I started my car after a warm restart, the tach delayed for a few seconds. The battery is orìginal, but I always keep it on a trickle charger when I'm not driving it. Car is garaged kept so I assume the grounds are good.
Any ideas? |

Old batteries in these cars cause all sorts of strange electrical symptoms.

Is everything else working fine and does it operate normally afterwards? I thought you had some other issues as well but i think i mixed up posts in my head.

Yes, everything else works fine. The tach works normally and no other issues. It just freaked me out because I never actually noticed it before. Stays on the battery tender when parked. Original Delco battery.

I wouldn't worry about it if that's the only thing you've noticed, could be normal and you just never noticed. If other strange stuff starts happening look at the battery possibility

Well I tried it a few times, there is a delay but its not much. If you hadn't mentioned it I wouldn't have noticed.

I thought the tach, speedo, and 4 packs did a full test sweep before they started? Or do you mean after that?

The speedo and tach don't, as the engine starts the gauges on the console sweep.
