QuestionQUESTION: I need to know how to hook up fused jumper wires to check cooling fans to see if they work. As of now they do not come on as they should. thank you
ANSWER: Hi Dwight,
The plug that powers the fan(s) has two wires, one is black usually and the other is colored.
The black wire should be jumped to the - post of the battery and the colored wire to the + post of the battery. be careful to not allow the clips to touch each other when the other ends of the wires are connected to the battery or you will blow the fuse.

QUESTION: Thank you Roland! One more question and i'll leave you alone. i hope i put this right! A code came up and it said catalytic system has low efficiency bank 1. I assume it is talking about the converter. I also assume that it has to be replaced. If so can i just remove the cat and put some glass pipes in it's place? Thank you!
ANSWER: Hi Dwight,
I would not recommend that you delete the catalytic converter. Aside from the increased air pollution that will result, I would be concerned that the engine control system will mis-interpret the lack of signal from the converter's oxygen sensor as a reason to modify the fuel input to the engine in a manner which will reduce the power or the economy of the engine. If you have a periodic state pollution control check program for re-licensing the vehicle would be subject to repair due to the lack of a converter. You will need to weigh the pluses and minuses.

QUESTION: I have a 1993 chevy p/u, v-6 tbi.It turns over and almost starts. ONe time it did start but quit after about 10 seconds. Dist.cap, plug, wires, electronic module are relatively new. Would a bad ignition dist. coil cause it to do that.
AnswerHi Dwight,
My advice would be to get a fault code readout, for free if possible, at a nationwide autoparts store such as Autozone. Then use the result of that to correct the situation. Don't 'throw parts' at the engine in the hopes of finding the weak link. The distributor coil is not likely to cause a time-dependent shutdown as you describe. I would suspect a sensor but you need some 'leads' based on a code readout.
