We sold our Volvo 2003Tand are installing a Beta.
We are not sure which direction the Volvo engine itself (i.e. the crankshaft) turned. Can a Volvo owner or mechanic please enlighten us?

One issue is that we drive a fridge compressor and an alternator off a shaft coupled to the crankshaft
I think the alternator can turn either way. (comments ???)
I worry that if we turn the compressor the wrong way we will wreck it.
