Engine won't start, what to check first before getting services of mechanic?

[jick.cejoco]

Good day sirs. Someone might be able to help. Vehicle is a gen 1 pajero (4d56 n/a).

Situation: engine didn't start today. Things I observed to be out of the ordinary are: indication lamps for the glow plug/heater, fuel/water separator & battery does not light up when ignition key is turned on. Hazard, turn signals, door ajar, radio & lights, however, are ok. Nagamit ko pa kagabi. Ok naman.

Checked fuses, all are ok. Will have to contact an electrician, but just wanted to know if there is something else I should check first?

Thanks for any advise.

check the fusible links (these are color coded wire fuses near the battery positive terminal. the insulation may look intact but sometimes the sacrificial wire inside is fried, the insulation is a fire resistant rubber like insulation similar to your flat iron cord) it is your power supply to the ignition switch (there are usually two circuits in the ignition switch aside from the starter circuit)
