I have a 2007 International pusher school bus and when I turn the key on
several lights turn on IE "wait to start","check oil","water temp","fuel filter", etc. come on as normal but never go back off after a few seconds(as normal). What controls these lights.I assume it's a self test of the bulbs ??

Thx,

Do they ever go off? Some take longer than others.

If it doesn't fit, FORCE it.
If it breaks, well, it needed replacing anyway.

Hello, We've got 4 of these same buses, so I can compare one to another. This one, these lights never goes out. "normal" is to have the lights come on with key and go off after about 2/3 seconds.(even before you crank the engine)
The problem lights are "wait to start","oil/water","warn engine",
"change oil","water in fuel", and "fuel filter". The other Asst lights on the dash act normal. I've even traded a dash cluster with a known good unit and these lights still come on and stay on, so it's got to be somewhere in the wiring ?
Is there a relay somewhere that controls the timing on these ? I'm wondering what normally keeps them on for a couple of seconds the turns them off ??

Thx, Marc

Ran into this one time on a 4700 truck. Ground issue to the dash. Loss of ground occurred, so it took it's ground through those same lights.
