hi again guys

I have a problem, my trip counter is resetting to 0 every time I switch off the car.

Everything was working perfect just before I tried to change the roof bulbs. While doing so, a very small spark developed (car battery wasn't disconnected).After the spark the bulbs did not light on anymore; either the bulbs got burned out, or else the car is not delivering power?

Also I noticed that when I turn the car key to on, besides the trip counter resetting to 0, all needles (fuel, temp, rev, mph) shake a little bit for about 1sec. This never used to happen before.

Gave a quick look at the car and all the other lights are working ... center console, rear lights etc...

anyone got a clue for the trip counter? it's very annoying and inconvenient. I tried searching the forum before posting but no success. recent changes to the car were the installation of an alarm, amp and sub , but everything was perfect after their installation.
