No power to the dash lights

First thing, check fuse box...all of them, as many new vehicles have more than one. If the fuse for the dash lights is good, turn your attention to the dash light dimmer switch. That has been the culprit for me a couple of times. If it's mounted in the dash, and not in the gauge cluster, then it's easy to replace. One question, did you recently install an aftermarket stereo? If so, did you hook up the "Dimmer" wire? That often shorts the dimmer switch...or in the case of my Honda Accord, the multiplex computer on the drivers side. What make/model/year is your vehicle? That would be helpful in trying to diagnose.

Can a fuse cause my 99 Trooper not to start

Answering for ENGINE will not Crank !
Or the starter motor is SILENT !
Is the IMMoblizer lamp in dash telling you why?
good questions, sure it can.!
all electrics on cars are fused, (cept starter main)
lets for get the engine, (for now)
by no lights? that mean head lights are both dead? (if yes we fix this first) {easy}
head lights work key off, so..... is panic fail, prime failure mode.
if you meant the cluster lamps only, why not say so?

if the HL are out, the battery is dead or its cables are rusted (4 ends)
or fuse blow out in main box.

if the cluster lamps are dead and for sure the CEL lamp? then the ECU has no power, and engine will never run with that dead. or IMMO lamp stuck on.
CEL = check engine light if , out,key on, the ECU has zero power.

the radio is dead , is one more prime failure.
head lights win that argument.. but i'd bet cab fuse box are dead due to PCD box under hood dead.

So, open hood, see the PDC (main fuse box)?
you check battery voltage with neg lead of meter to body metal.
it reads:
12.6 vdc or more rested is a charged battery,.
$10 meter at walfart works.
if not, bingo. bad battery cables or ground. (the cables have 4 ends,and all 4 ends can rust or even be loose)

so next check the voltage in the main box at all main fuses.
i'd bet one fuse has 12v on one side and 0v the other is a clearly blown fuse.(there)
if you need a schematic we have it.ask

the symptoms are lost main power.
the tests are easy.
with any cheap voltmeter every made.
got one?, or must we work blind?
No cranks (is IMMO active?)
no head lamps, fuses blown for them or mains blown
CEL lamp dead in cluster key on , ECU fuses blown
or cluster fuse blown.

from your limited hints, id say them mains are blown.7388ecf3-ec1e-4fdb-b172-b274fca78a06.jpg25917427-q3trmxyjzvqfc2lfsqsrd2xd-5-2.jpg

FL1 is the main fuse.
got 12vdc on both sides if fuse? if not all is dead. the fuse blows, changing out the alternator not pulling battery neg lug(very common reason)

Where is the 1997 Isuzu Trooper inertia fuel button located, cranks over will not start?

one more anony post, making help hard if you have 2 or more post.
see? why do that?
why guess? why not use a real book on topic
well if any engine stalls, the CEL glows.
the CEL glows for the stall self tests. it glows telling you
the ECU is ok and has 12vdc power.
get the schematic for your car.
and find out why power is lost the EFI system. this is not the nebulas inertia switch,
what does SEEM mean.??? using a voltmeter works, looking and guessing not. use a voltmeter to find where power is lost.
your not stumped,
you dont have a meter
and dont have the book
so log in the

btw2: no engine size stated, and guess what.
the schematic for all parts are different. fuel and electric.
if you go on line
the ask,year, make ,model and ENGINE.
can fix any engine, until you know what is there. impossible.
(unless you use BASICS for OTTO Cycle engines)
lets do that. for fun
got spark? no
got CEL ,no
Got power to ECU , no.
so you use the voltmeter to see where power is lost in this power feed system. (its a tree construct)

now a random answer, 6 cylinder engine.
Fuse C8 or F3 blown.
engine, and ECM F3 powers the whole ECU.(PCM)
main relay output wires dead. red/blue wires. killing all spark and fuel.
fuse C10 kills he CEL lamp dead.
is uses a volt meter, (walfart for $10?)
and both sides of these fuses read 12vdc to ground.
if not fuse is blow or input to this box is bad.
the engine bay fuse box runs the whole cab box.
do the head lights work.
are there other things dead , not stated?

one of these fuses or relay is dead.
or the dash lamp fuse blew, yous said they were dead
you key on, the CEL glows power to the PCM is below right.
if the fuse is dead both sides you blew the eng.bay main fuse.

Dash lights or navigation light do not come on when the key is on

first check that the dash light dimmer knob is not turned to very dim (far left). It is located in the dash instrument cluster slightly left of center between the tachometer and speedometer near the bottom edge.

If that seems okay, check out the No. 13 fuse in the passenger's side under dash fuse box.

If the fuse is okay, you may have problem with the driver's multiplex control unit. This unit controls lighting for multiple other lights and switch indicating lights.

Circuit Braker
A bimetal circuit breaker is located in the joint box, which is just above the interior fuse panel. This circuit breaker protects the rear window defrost circuit and is the plug-in type.

The main fuse block is located inside the left side of the engine compartment near the battery. There is also an interior fuse panel located just above the left side kick panel.

Fuses Replacement

CAUTION Never replace a blown fuse with one of a higher rating. Severe damage to the vehicle, electrical harness and components, as well as personal injury or even death could occur.
Main Fuse Block
(see Figure 1)
  1. Disconnect the negative battery cable.

Fig. 1: Remove the fuse box cover, located in the engine compartment, to access the main fuses for the vehicle
  1. Unhook the lock tab from the main fuse block cover and open the cover.
  2. Pull the fuse from the main fuse holder.
  3. Installation is the reverse of the removal procedure.
Interior Fuse Panel
The interior fuses simply unplug from the fuse panel. Use the fuse puller tool provided with your car to remove fuses from the panel. The tool is located on the back of the interior fuse panel cover.

The main relay box is located on the upper left-hand side of the firewall (bulkhead). There is also a relay box mounted inside the vehicle under the left side of the instrument panel.

Relay Replacement
  1. Disconnect the negative battery cable.
  2. If replacing a relay at the main relay box, disconnect the electrical connector and slide the relay from its mounting bracket.
  3. If replacing a relay at the interior relay box, simply unplug the relay.
  4. Installation is the reverse of the removal procedure.

I hope help you with this (remember rated this help) Good luck.

Car just died, electrical system gone

there is no such thing as a main battery fuse.
seems like a wire has come undone under the dash and shorted your car out.
