No, the Earth is not spinning backwards. It rotates on its axis in a consistent direction, which causes day and night.
It may generate power if you run it backwards, but it won't cool properly
what exactly happens to your alternator when you hook up your battery backwards?
spinning
first what kind of car is it ? Alternator can't be put on backwards!
An alternator does not need a gauge to work. It is used to monitor the output of the alternator.
Yes, everything on the Earth's surface is very slowly, moving backwards.
The wires in the plug are backwards. switch them around
A quick way to check alternator on any vehicle is while engine is running,carefully touch a screwdriver to the spinning part (armature) of the alternator. If it is magnatized, it is charging. If not then alternator is not charging. The voltage regulator (the thingy that tell the alternator to charge) is built into the alternator. Replace the whole thing with a rebuilt unit.
Should be a max of 5-6 bolts, and a electrical plug. Disconnect neg. battery cable. Unplug, plug from alternator. Remove belt from alternator pully. Undo bolts holding alternator, should all be visable. May have to wiggle or twist alternator to get out after bolts and plug are undone. Now work backwards to put back in. I had to put my belt on first and tighten the bolts.
When you connect the battery backwards you can cause major damage. You can blow the alternator or its fusible link. You can destroy electronics, particularly the various computers - and these are not cheap.
The Earth rotates, not the stars, so unless the Earth starts spinning backwards, no.
