Ignition light wont come on ,battery fully charged

Starter motor or solenoid could be at fault check the battery is fully charged first

First make sure your battery is fully charged. The charger on lawn tractors will not keep the battery fully charged as they just produce a light charge. Check battery before the starter but if battery is fully charged then it's possible the starter could be bad.

You out the alternator in incorrectly. please triple check the installation of the alternator.

If the battery is fully charged and your getting a clicking sound when you turn the key, it sounds like you have a bad starter solenoid.

it looks like you have a fusible link burn or open circuit
with a test light find out witch circuit is missing.
the starter have direct current from battery and ignition current to starter solenoid. maybe the problem is ignition switch or wires
hope it helps

If your battery is charged, could be a starter or ignition switch problem.

There is a magnetic switch on the 'park' position. The car only starts or releases the key in 'park' is enabled. Maybe this switch is not working! Try to replace it!

hi may i suggest you have alternator output /charging checked also considering age of vehicle ? if origional battery ? have the battery checked for charge storage it may be failing to hold charge which would explain the problem you mention regarding use of h/lights slows starter rotation ?

When the amp meter reads 0, then it is no longer drawing amps and is fully charged.

i hope this was helpful,
