Lights not working on Star golf cart. Fuse is good. How do I check switch?


Buy or borrow a voltmeter, check the voltage across the batteries, the light bulbs, and the switch open and closed. The full battery nameplate voltage should appear across the battery, and across the light bulbs when the switch is closed, and across the switch when the switch is open. If these are not true, you need to look for breaks in the circuit. To do that, turn the switch on, check the volts across the battery, keep the negative connected to the battery, but disconnect the positive voltmeter wire from the battery, check the voltage on both sides of the switch, if they each match the battery voltage, move on to checking the voltage on each side of the light bulb. If one side of the bulb matches the battery voltage and the other side is zero the bulb should light. If not Change the light bulb. If both sides of the bulb match the battery voltage, then there's a break in the wires between the bulb and the negative side of the battery.
Now going back to the switch situation: with the voltmeter negative still connected to the negative of the battery, if one side of the switch matches the battery and the other side of the switch is zero, either the switch is off or broken. Turn the switch on and off a number of times measuring the two voltages each time. If you can't get both sides of the switch to match the battery, the switch is broken, replace it. Good Luck GooseBay_Camper.

2008 Volvo s80 left headlight not working, changed the bulb, the HID/LED kit both sides and all the fuses looked ok but the left headlight still not working any help please?


Place a meter on the supply line, (12Volt!), if voltage is there, suspect the ballast unit, if not trace the supply back to the switch and ignition supply.

Low beam not working


I would look at the headlight switch test the switch at the connector for continuity and or voltage.Always look at the simple and easiest areas first, bulbs, fuses, relays, then the wiring to the switches, then the switch.

No front parking lights, but all other lights working fine.


Start with checking the fuse if that's ok then remove the bulbs and look at each socket inspect for corrosion .No corrosion then replace the bulbs( you never lose anything if later on we determine that it was an open or a bad switch by having extra bulbs) . If that doesn't do the trick. Then use a digital volt meter( DVM) and check for battery (power(B+) at each light socket(wires entering the socket and the socket itself), when the switch is on. If B+ is not present then you have an open in the circuit or the switch is defective. Remove the switch and use the repair manual to show you which wires on the switch to jump to make the lights turn on . If by bypassing the switch the lights work you need a new switch. If not you have an open in the circuit and that will require using the DVM and back tracking the circuit to find the open. 90% of time its the switch. Good luck

Side lights dont work


Fuse sure didn't play, bulb is unlikely to be all bad. Check the turn signal switch, first find the turn signal switch plug, put the key to ON file, in trying to find a turn signal lamp switch wire (flash to the thread) will this wire with no light ON one side of the turn signal line connected to see if a turn signal light, the light is turn signal switch is broken, or the plug contact undesirable, don't light it is turn signal switch to light ON one side of the light path, in order to determine whether the light bulb is broken can open a small lamp or led brake lights to borrow their wire leads to a turn signal whether turn signal light, so you can determine whether the light bulb not bright side is broken.auto diagnostic tool.

Rayovac 360 sportsman lantern wont work


Since batteries and bulbs are new/ok, check for a bad connection. In older version using 4 lantern batteries, open the battery compartment by unscrewing the knob on top of lantern. The lantern bottom comes off once unscrewed (of course you did this to change batteries). There is a "C" clip on the lantern center shaft; remove this by prying with screwdriver or with pliers. Carefully raise the battery contact plate and check slip-on wire connections. Clean as needed (Scotch-Brite works well) and reconnect. Squirt some contact cleaner in exposed switches, work switches back and forth. Inspect circuit board for obvious corrosion or damaged parts (this damage may "total" the lantern). Re-install plate aligning grooves with ribs. Install batteries and test.

My light blew out I changed the bulb but it is still not working


I suppose you should have checked that bad bulb and the new bulb in a working table lamp. If they work there then the door switch for the light may be defective or a connection has opened in the supply voltage. 90 percent of electrical problems are not shorts -but opens.. OPPS! something is missing. The voltage is not getting there

Coleman rechargeable lantern: Charged overnight - not working, replaced bulbs - not working. What could it be:


Check the battery with a volt meter to make sure you have the correct voltage. If not, replace battery. If correct voltage, bypass switch to determine if it is good or not. If not, replace. There really isn't much to go wrong on the lanterns except the bulb or battery.

My lighywedge book light fell into the floor. Now it doesn't work. Vicente, from Spain


You know the nature of LightWedge Book Light, very fragile. After falling it might malfunction and it might simply needs a replacement if you cannot get a trade in on the broken product.

I had a bad experience like this sometime ago and I really wept over it till I got money to but a new one.

Sorry and good luck.
