Question about Vehicle Parts & Accessories
No starting cause the battery has been drained i dont know by what but something is distorting the electrical current of the vehicle.
Hi I\'m Peter, I hate to say it but it sounds like you are in a bit of work. This can be a nightmare that makes some mechanics run. First of all you realize you have a short to ground somewhere and the bad thing is we don\'t know where. What you need to do first is lets start looking for something that sticks out a wire that\'s hot a relay, etc that is hotter than normal or maybe discolored from heat. Maybe use the old sniffer and cruise around smelling all over the car. Get a case of beer and invite the friends over heck make it fun if you can who knows the friend that you may want to kill every other day may actually have a great nose and smell something no one else does. A little joke but a little serious too. Some people are more sensitive to smells than others. If nothing out of the ordinary has been found here comes the pain in the butt part. Go to your fuse box or boxes if you have one in the vehicle and the engine compartment and one at a time you need to pull the fusses and determine which is the supply side and which is the other. Of course you will have voltage on the supply side but if you have voltage on the other side and there is no fuse there then you need to get a schematic and trace that wire you have a short to that wire. You can also looking at the wiring schematic determine where all of your grounds are. Disconnect them one at a time and test them if you have voltage then trace it back till you find where it is getting voltage from and there is your short. Don\'t get discouraged if you pay a shop they will usually charge you by the hour on this type of electrical job and they may have a minimum of hours or ask you at how many hours do you want them to stop if they have not found the problem and hope you have an honest shop because they could say ok we tried for three hours and haven\'t found it that will be $95.00 an hour for 3 hours please. Out almost 300.00 dollars and no closer. Last desperation and I hate to even mention it because it sounds like a cop out is to put a battery cut off switch on your vehicle but then every time you want to start the car you have to turn it on then when you shut the engine off you have to turn the switch to disconnect. That\'s a poor man\'s fix Remember this could be anywhere , one time when I was working in Colorado at the airport I had a fleet vehicle that was hardly used and a field mouse had crawled up behind the dash and chewed the insulation off a hot wire and it was touching the metal frame of the dash. Sneaky little guy but I found it and fixed it because I realized my whole dad gum dash had power and every time I touched a ground anywhere to a metal screw or part of the dash it would spark.. It could be in the solenoid for the starter, a relay switch that has stuck, anything so eat it like an elephant one bite at a time and try to narrow it down to a particular circuit then go from there.
