Denny's post is in reference to 1947-1953 Advance-Design trucks, with regards to being able to use a hand crank.
Stan's question to Denny regarding the location of the in-dash radio in Denny's 1953 truck is not very relevant with regards to a 1946 truck.
A 6v engine should easily start, hot-or-cold:
IF, your 6v engine, and 6v starter, are in good shape,
AND, you have good 6v battery cables/straps (00 gauge to 2 gauge),
AND, all the connectors and connections are secure and are clean/shiney
(with antioxidant conductive-grease to assure good connections over time)
This is based on my several decades of 6v starting experience.
And, based on one brief and unnecessary 12v-conversion interlude - due to my erroneous/y thinking that reproduction part vendors were selling true 6v battery cables AND straps (Jim Carter and other vendors were not, back in the 70s/80s).
