How to check for a no spark condition on older vehicles with distributors

Simple: First thing is get a test light, hook the test light up to the negetive side of the battery. take your test light and touch it to the positive side of the coil ( should have a + sighn on it ) have someone turn the key on and look for the light to come on. if it dosen't then check for blown fuses or brokenwires to positive side of coil. If light does come on move to next step..
now hook your test light to positive side of battery, touch your test light to the negetive side of the coil ( it should have a - sighn on it, then have an assistant spin the engine over if the light blinks rapidly and still no spark from coil then the coil is bad. if there is no blinking light then the ignition module or points are whatever controls your trigger to the coil is bad.

Remove plug from light bulb, using 12 volt test light hook up ground to negative side of battery,then touch probe on positive terminal to make sure test light is functional.next- turn lights on and then probe the plug at each terminal- there should be one wire that has power and the test light should light up. If the test light lights up then you need to test the circuit ground for the wiring harness. So remove the test light clamp and put it on the positive post of the battery. Now retest the test light by touching the probe on the negative post on the battery and the test light should light up. Next with the headlights off-probe the other terminals and if there is a good ground in the harness the light will light up- if not then there is an open condition in the headlight harness- a broken wire or a bad system ground.If both tests are performed and either condition does not happen then a wiring schematic will be needed to perform the repair. This is after all fuses are presumed good.

i have a new battery but its dead all ready how do i find were the short is at

Unhook the battery on the positive side. Use a test light and hook it to the positive battery post,and touch the unhooked positive cable. If you have a draw,it will light up. The best way to narrow it down from there,is to start pulling fuses..one at a time..,untill the test light goes out.Then check the manual to see whatt that fuse runs power to,and go from there.

How do I connect the wiers form the to the starter

First off, if you are unsure of which are ground wires. disconnect your battery then hook a test light to the positive on the battery, touch each of your wires if the test light lights up mark that wire as a ground. next is finding your ignition wire which should have a smaller eyelet than any of the others.everything else hooks to positive on the starter

2000 dodge dakota sport blower motor won't work

Hi my name is Allen!

This is a very hard motor to get out!

This will save you time, if you have a test light and jumper cables, hook the jumper cables to the battery, then hook your test light to the positive side of the jumper cable, turn the ignition key on and turn the blower motor on. Next at the blower motor connector touch the test light to the negative side of the connector if the test light, lights up you have a good ground. NEXT; move the test light to the negative side of the jumper cable and test the positive side of the connector if it lights, you have power coming to the motor, if you have both power and ground you need to replace the motor, if no light on one side you need to repair the one that doesn't light up.
