I'm looking for help in changing the battery warning light on a Prado KZJ 78W. The warning light is not coming on with the ignition turned on and the alternator isn't charging. I have the instrument cluster out, but the bulb is in the voltmeter and I'm a little concerned in damaging this unit. Any help would be appreciated. I don'nt know if i should have checked the alternator first, but the cluster has been removed so I should confirm the bulb is ok before re-installing it. Thanks.
