Installed motor in my '74 chevy pickup today and attempted to make truck run. After some time I noticed that the starter is cranking the engine backwards. I have never come across something like this before. The ignition wires were eaten by mice so I wired up a pushbutton starter. The hot battery terminal still runs to the main solenoid post. The post on the right (if viewed from the front of the truck) is run to the pushbutton and this cranks the engine. The other post is grounded. Any reason why this would cause the motor to crank backwards?
I had that happen one time too! I hooked up the battery backwards and.....my engine started up backwards! I tried to drive off, but I went backwards (trhu all 4 gears!). The faster I went... the fuller my gas tank got! I KNEW something was wrong, so I backed in for gas....and as soon as I put the nozzle in, it sucked the gas outta the tank! When I got home, I told my wife about this and she really felt bad for me. She asked if there was anything she could do to make me feel better....and I said yes!
As we were having the BEST sex I've ever endured.... she ruined it by screaming "I'M GOING, I'm GOING"!!!!!! Don't even ask what happened when I had to "go"!
JohnyR17,
I think you are looking at the timing mark backwards. "B" is for advanced and "A" stands for after TDC. Just look at the fan blades while the engine is turning. The fan should be pulling air through the radiator.
Have Fun

Did your battery go dead before starting? I mean did you have to jump start it or use a charger. I had a 78 Chevy truck with a 350 in it that turned over backwards. It turned out that the battery had been dead and a guy I know tried to jump start the truck while I was away.
To make a long story short he had trouble using the jumpers as though they were hooked up wrong. He hooked it up as positive ground and everything seemed fine except the truck was turning over backwards.
The battery had gone stone dead from being parked all winter and actually changed polarity.
I talked to the auto parts dealer where I got the battery and they gave me a free of charge replacement. He then told me that mine was not the first to do that and that there had been a whole bunch of people returning batteries for the same reason. Check to see if you put a different battery in if it turns the right way. Good Luck.

Get some side draft carbs hooked up to the exhaust ports and run some new exhaust pipes straight off the intake manifold and right through the hood. Next, flip the rearend over and problem solved. HTH
Note: Don't play certian CDs in the CD player as they will play backwards and reveal satanic messages. The only person I know of that did this said the messages made him make posts like this on bulletin boards all over the net. :drunk:
Hello, I dont know if a battery can be reversed in polarity, and even if it did, the starter still would not engage the engine flywheel. If you somehow managed to get the engine to turn over backwards.....IT WOULDNT RUN, YOU WOULD be sucking air from the exhaust all the way back through the engine and out the carburetor !!!!!!!!!!!!!!!!!!!!!!!engines dont run on air. Oh yea if the said engine did run, a battery charged backwards would kill an alternator, computer and all associated electronic components
:spank: :nono:
First, only a permanent magnet starter could rotate backwards,one with field windings will always turn in the same direction because the field polarity is changed with the reverse current. If it is a permanent magnet motor, as stated the bendix wouldn't engage. You are apparently interpreting the rotation incorrectly.
