Do semi trucks use 12V or 24v?
In the U.S., trucks today are 12 volt. In years past they would be 12/24 volt wired through a series/parallel switch to provide 24 volts for the starter and 12 volts for the rest of the system. Today they have one, two, three or four 12V batteries hooked in parallel to give high current for starting.
Can you jump 24v with 12v?
Jump-starting a 24-volt system from a 12-volt system won’t work if only one 12-volt battery is available, but if the 12-volt truck has two batteries, it becomes possible to produce a 24-volt supply.

It just allows the engine starter to crank over but for the engine to run the engine ECM needs power and ground, fuel, engine RPM and speed signal, along with the air/fuel/ compression/etc basics. Jumping the solenoid just bypasses a faulty solenoid. Test for power to the small S terminal at the solenoid while in the cranking position.
