When i jump off my 2001 Mitsubishi Diamante my brake and battery lights are on at the same time, but when i disconnect the jumper cables the car will only stay running for a few minutes and then cut o

Once jumped n the jumper cables are removed it dies again. I would think it's not charging , alternator problem maybe .Is the battery light lit on the instrument cluster ?

1. Adjust the rear drum shoes for minimal clearance. Note that the linings may need replacing.

2. If necessary (and may not be) replace the two hand brake cables. Cables can rust solid and jam, but rarely break.

3. Remove the center tunnel cover between the front seats. Adjust the cables so the hand brake handle has minimal upward movement.

4. Put it all back together.

You must have not connected all the wiring or misconnected it.

Bad ignition switch or bad ground to the battery.

did the timing belt slip?

It appears that the 2001 mitsubishi diamante is an interference engine, so it is possible that you have damaged your valves. Have it inspected by a mechanic before operating the starter.

1. Disconnect the negative battery cable.
2. Drain the engine coolant.
3. Remove or disconnect the following:
   
   Timing belt Alternator brace from the water pump Timing belt rear cover Water pump mounting bolts Water pump, gasket and O-ring
   

To install:

1. Install or connect the following:
   
   New O-ring on the water inlet pipe. Coat the O-ring with water or coolant. Do not allow oil or other grease to contact the O-ring. Water pump to the engine block, with new gasket. Torque the mounting bolts to 10 ft. lbs. (13 Nm) Alternator brace on the water pump. Torque the brace pivot bolt to 17 ft. lbs. (24 Nm). Timing belt rear cover Timing belt Remaining components
   
2. Refill the engine with coolant.
3. Connect the negative battery cable, start the engine and check for leaks.

Hope this gets you back on the road.

this issue sounds like a grounding issue, teh main clue being everything gets dimmer. sometimes an additional ground is a faster repair than finding and resolving under dash issues.

This issue will likely NOT be battery or alternator.

Love the right rear tire clue, and it should not be related..

in order to get the code for that car you are going to have to call the dealership. and give them the specs on your car and maybe even your vin number.
