6.5 turbo

Does anyone know whether or not the dashboard is illuminated during daylight hours. In certain lights, such as driving into the bright sky it is very difficult to read the speedometer. The dash lights up at night OK but is still dimmer than I would like even with the dimmer switch on full. No fuses are burned out.

Have changed the starter and fly wheel. Think I have starter hooked up wrong. It has three wires. Also, when hook up batteries to try to start, batteries spark and Glow plug stays on all time. Think I might have starter connected wrong

My husband it changing the brake pads and rotor on the front and needs to know how to get the rotors off.

The engine has a regular miss and low compression in one cylinder. Will I damage the catalytic converter if I drive it?
