twobjshelbys Posted May 16, 2017 Report Share Posted May 16, 2017 In spite of the test I still suspect the battery. Link to comment Share on other sites More sharing options...

ARCxAdge Posted May 16, 2017 Author Report Share Posted May 16, 2017 Where would I find the clutch safety switch and how would I rectify that Link to comment Share on other sites More sharing options...
SAI-Steven Posted May 16, 2017 Report Share Posted May 16, 2017 In spite of the test I still suspect the battery. Easiest way to test the battery is to turn on the headlights and crank the engine, if the headlights go dim you need to replace the battery. Unless the battery is relatively new, you might be able to charge the battery. Relatively new to me is under 18 months. Steve Link to comment Share on other sites More sharing options...

ARCxAdge Posted May 16, 2017 Author Report Share Posted May 16, 2017 I was told that even though the battery tested good OT isn't at full capacity so there may not be enough to start the engine. Do you guys agree. Link to comment Share on other sites More sharing options...

Do you guys agree. Perform the headlight test I described above. It will answer your battery's health question instantly. Link to comment Share on other sites More sharing options...
ShelbyGT5HUN Posted May 17, 2017 Report Share Posted May 17, 2017 Or just jump start it. Link to comment Share on other sites More sharing options...
Don Johnston Posted May 17, 2017 Report Share Posted May 17, 2017 Do a battery amp load test to see if it is healthy. Voltage reading is useless. Then check to see if the alternator is working properly. If just one diode is out, you will not get full output. Bottom line is that I also suspect the battery being too old, too under rated(amperage), or having a cracked plate. Also check, as mentioned, starter relay and fuses.

mhr1961 Posted June 2, 2017 Report Share Posted June 2, 2017 OP, did you ever track down what the problem was with your car not starting? Link to comment Share on other sites More sharing options...
ARCxAdge Posted July 5, 2017 Author Report Share Posted July 5, 2017 No I haven't tracked down the problem. I did the headlight test and it is good I tried a brand new battery and still didn't start. It will start of I jump it. I'm at a loss. Link to comment Share on other sites More sharing options...

Glenn Greenwell Posted July 5, 2017 Report Share Posted July 5, 2017 check your ground wire on the car, look for all the simple stuff. GG Link to comment Share on other sites More sharing options...
ARCxAdge Posted July 7, 2017 Author Report Share Posted July 7, 2017 I'm really stupid when it comes to car mechanics where would I find the ground wire plus it won't even jump now Link to comment Share on other sites More sharing options...

mhr1961 Posted July 7, 2017 Report Share Posted July 7, 2017 I'm really stupid when it comes to car mechanics where would I find the ground wire plus it won't even jump now If you have been jump starting the vehicle that can sometimes fry a fuse. You are admittedly not very knowledgeable, so if I were you, at this point I would either have somebody who is knowledgeable come check the car out or have it towed to a qualified dealer and have it properly checked out before you perhaps do further damage to the vehicle. Best of luck to you and let us know what was causing the issue. Link to comment Share on other sites More sharing options...
Don Johnston Posted July 8, 2017 Report Share Posted July 8, 2017 Anything on ODB II? Might show a code. I wouldn't do a lot of jump starts with todays cars and their low voltage computers. It could fry something and make matters worse. Recommendation for an auto electrical shop or a reliable Ford dealer service dept. might be the best way to resolve the issue.
