I went to replace windsheild washer pump only to find pump wasn't problem. I have current to the pump enough to light up a test light, but not enough to run pump. I aslo check the current with a small light bulb and it will not light up bulb. Where should I start to look for a bad connection and how do I go about finding the problem.

I am sorry that I can't donate money for I have not worked in 26 months and just can't spare any.

Your best bet would be to get a multimeter and see what your voltage is on the power side.I would also check the ground side of circuit hook your test light to the power side of your battery and touch the ground side of the connector see if the bulb light's bright. But the best thing to do would be to get a multimeter so you could see what voltage your getting and you can check the ground side with a ohm's reading.

I have done that and the bulb will not light up. My test light shows power andthe ground shows it is working. I have voltage just no amps. I have done all checks I just need to know what is next move for me. Do I trace wires back or do I check switch?

Because this thing lights up my test meter yet it will not lihgt up a small light bulb.

Before you start tracing wire's etc you need to get a multimeter and see what the voltage is actually on the power side and then with the ohm's setting see if you have less then 2 ohm's to ground. That way you know if your looking for a bad ground or the switch or wire to the power side of the washer motor. You will need a multimeter anyways to check the switch. So do yourself a favor and get a cheap meter. Or you will just be guessing on what's wrong or which way to go about repairing it.
