Check battery and chassis earth connections are ok.
Check for 12v power at the fuse/power disrtribution fuse bus; - if no power there, trace circuit wiring back to battery.

1993 Suburban. Why do only the headlights and dome lights work?


So when you turn the key to on, no dash warning lights and gauges turn on? Did you check the fuses with a voltmeter or test light? With key off, some fuses would have power at all times-brake lights, headlights, horn- but with key on, all fuses should show power.

Just off the battery is the Battery Junction Block, where the power is distributed to various circuits through Fusible Links. These connect to battery power with eyelet connectors at the Junction Block-looks like 5 or 6 Links leading off the Block. Even the small wire from the battery to the Block is a Fusible Link, but if your headlights work, this main Link must be okay. One of the Links from the Junction Block would be to the ignition switch. If your ignition switch has power, you may have a bad switch, but you need to check if it has power first. If no power to switch, check the Fusible Links. The diagram I am looking at does not show which one it is, unfortunately.

My 2002 saturn has no power, or even dash, or dome lights.


Check for a fusible link going either to the starter or inside the car on drivers side by fuse box they are usually found by either a little round black piece on. Them that looks like a fuse or a larger wire that has a smaller wire on the end of it I can tell you for sure most fusible links on Chevy's are brown anecdotes he go to the starter the older Chevys anyhow

I accidentally hooked up jumper cables backwards when I was trying to jump start my 97 Ford Escort. Needless to say, it was not good. It started to spark and caught on fire. I was eventually able to get it...


I bet you saw some dramatic sparks when you hooked the jumpers up backwards!
The good news is that if your ignition switch was turned to the "off" position when this happened, the fix may be simpler and cheaper than you think. This car has one or more "fusible links" in its primary wiring. They may look like a thick piece of wire, but they act as super-fuses in the the case of large-scale power shorts and the like. Fusible links are typically in-line, so you won't see them in either your under-hood or under-dash fuse boxes. If you're lucky, you blew a fusible link right off the bat, saving the rest of your electrical system from serious harm.
If your ignition was turned to the "on" position when the battery was hooked up backwards, you have a more serious risk that you damaged your on-board computer. However, even if your computer were fried, your dome light, your hazard blinkers, and probably your headlights and turn signals (different circuit than the hazard lights, believe it or not, even though it's to the same bulbs) would continue to operate.
I'm going to recommend that you should check for one or more blown fusible links. Good luck!

1989 chevy k-1500 headlights taillights parkinglamps dome light and dash lights will not come on and not getting any power to the headlight switch. and have replaced headlight switch and relay and there's...


Usually the power feed to the headlight switch isn't fused. It will come from a fusible link under the hood. On the right side of the firewall there is a black plastic cover, under it are the fusible links. Check here for a possible blown one. I would also suspect the headlight switch may have originally caused it to blow if thats the case. If you have already replaced the headlight switch, replacing the fusible link should repair the lights. Make sure you replace the fusible link with the same gage wire and same length.

Battery and connectors are new. NO POWER to the truck at all. No lights dome lights nothing it's completely dead. I'vev checked the fuses but someone mentioned a "master fuse" someone else...


Check for good ground.try attaching jumper cable from negative side of battery to engine block.If no result attach to body or frame of vehicle (area must be paint free) if that does not work check positive cable for power going to starter. If power is present replace starter solonid .You may have a fuse or fusable link but check these items first.

Battery is charged, when key turned nothing happens, and the headlights will not even come on. Almost appears that there is no power to the dash. Brand new battery and alternator.


try cleaning or replacing battery cables. any corrosion can degrade the voltage. check the wiring behind the fuse block also. (loose wires..) your chevy may also have a fusible link between the battery and the fuse block.

While putting electric window down engine stalled and all electrical went dead even dome light everything is completely dead electrical and batteries good


check the main fuses (bigger fuses in the engine compartment fuse block)
if they are ok, check the ground wire from the battery for defects and the terminals and connection to the chassis for corrotion

2003 windstar no power past the battery ?


I would check with vom voltage at battery terminals and at starter to ground. Is possible could be a fuse or fusable link but I think the positive goes straight to starter and power distribution fuse or fusable link
