91 hzj75 1hz warning lights

[Speshy]

gday all,,,, got a 91 hzj75 with 1hz,,, the filter, and air filter , battery lights are staying on,,,, along with the timing belt light,,, just had a new belt installed and have been trying to reset it with the little button on the cluster with no luck at all,,,
Have checked both the air n fuel filters( both new) ,, checked to see if the fuel float was working n it sets the buzzer off when manually lifted,,, so wouod think thats not the problem,,,,

Any ideas or thoughts as to where to start looking greatly appreciated,,,,

remove battery + for a few minutes - see if that helps. Switch ignition on and off a couple of times should reset fuel/water lights. resetting the timing belt light is a fiddle with odo reset and ignition.

Check your alternator. No broken wires in the connector?
Put a voltmeter on the battery When you switch off the engine, the voltage should drop a bit.
Any faulty earth connections?
