Sharp Wizard 9600-II won't start after replacing all batteries.

I suggest that you remove the battery and use the charger only in turning on your computer. If it turns on just fine without the battery then you would need to replace the battery. If it doesn't then it's either the motherboard or the charger which has a problem.

Check your start 20-30 amp fuse, Should be on right side of motor, sitting on it.

Check for spark of smell of gas on the plug when you try to start it. That will tell you if it is fuel or ignition

First you always test things & never replace anything

When you understand how things work & how to test
them,then they have to fail a test in order to need replacing

I would think Fuel Pump--if it quite while driving
Put a gauge on the motor if you have a shrader
valve to do so

Seldom do you need to replace a dist
The parts inside can be diagnosed & replaced
if you can source them

Things like plugs,wires & such you leave until you
know if you have fuel pressure,spark & so on.

Once a vehicle gets to 20 years of age you start
checking for wire corrosion such as around fusible links

Never forget the battery & it's cables & the internal
corrosion possible there

Worn ignition switch a possible

You say won't start,so I assume the engine
does turn over?

Battery was completely dead ? after how long , over night , or just out of the blue ? These year GM vehicle's 03 to 06 have instrument cluster problems , draining the battery . Do you know what parasitic draw is ? Google it . They used lead free solder constructing the electronics , an after a while it causes silver migration .

Check you safety switches, brake, neutral, seat, blades, and reverse (if equiped). Then if that does not work I check the starting solinoid and the ignition switch.

Friend, try to replace the battery. If it doesn't work try to press firmly the LCD connection interface underneath the screen because such unit has lossen connection.use T6 screwdriver to open the unit then slowly firmly press the LCD connector on the interface. Such thing will solve the problem. good luck

If the pda was made in 2005, it's likely that there is a small watch battery somewhere which saves your settings, date, time, etc.
If this "CMOS battery" needs to be replaced, you're probably losing all of those basic settings whenever you let the main battery lose too much of a charge.
Hopefully, it's easy to access.

When you held the start button down and pressed the reset, did you get a message appear ? as per the manual
