Question
QUESTION: My son has a 1984 Ford F150. A guy told him his starter solenoid was going out. So we got one. Replace it, but in the process he did not disconnect the terminal. He dropped the positive battery cable on the voltage regulator, Thinking why the truck had to power inside. No Luck, Replace the brain box on the left fender well, No luck. Removed we believe all the fusible links. No Luck. We have no power to the inside of the truck what so ever. No Head lights either. We did run a jumper wire straight from the battery to the fuse box and lights came on. Turned ignition on and wire got really hot. We did ck all fuses okay. Checked alot of wire okay. Please help . I am all out of ideas. Thanks Paula

ANSWER: Hello Paula I really don't understand you question. Was all fine with the truck before the solenoid was replaced? The jumper wire more than likely became hot with the ignition on because it was to thin to carry the right power into the truck. Make sure to check all connections on the battery and solenoid for a good connection. There are two sets of cables on the truck, one to the starter and the other to run all the accessories on the truck. Let me know if the truck had power inside of it before the solenoid change and if everything was working. If need be you can send your fax number to my email cardoctorc@aol.com and I will fax you over wiring diagrams, fuse, and fusible link locations for your truck.

QUESTION: Okay let me start over i am sorry i am do not always talk automotive lingo. A gentlemen told my son because occassionally he would have starting problems his positive battery cable was loose and needed to be replaced so he replaced it. Then it happened again and he said the starter solenoid needed to be replaced so we replaced it. Upon replacing it we hooked up the wrong wire to the neg side which caused no power to inside of truck but he also dropped the positive battery cable on the Voltage regulator. We replaced it, Since the inside still had no power we cut out all but i think 1 or 2 fusible links, replaced the brain box and the coil. I found the starter solenoid hooked up wrong and corrected it and then received power to the inside of the truck, but now when truck starts it automatically shuts off almost like it is not getting fuel, fuel filter is fuel of fuel, it just will not stay running for nothing. Can u please help me.

Answer
Hello Paula double check your grounds. There is a small wire that goes from the negative battery cable to the body. This ground is re.sponsible to control the injectors, fuel pump and ignition system. Also there is a green relay by the starter solenoid that may have got knocked loose or damage when changing the solenoid. This is the EEC relay and is responsible to power the same components that the ground wire grounds. Get back to me after making these checks. If need be you can email me at cardoctorc@ao.com for any further questions or information
