The tech Ray talked to mentioned increasing the wire guage to a bigger wire to the starter and it got me thinking.... this seems to me to be a good idea.It would in theory make our starts less demanding on the battery thus increasing battery life. Does anyone know of a reason it would be detrimental to do this or does my theory thinkin not inline with practicality.
That would seem to be correct. If using basic Ohm's law, the bigger cable typicaly would have less resistence and thus allow less heat from the higher amps, greater amperage flow to the starter, etc. All good and any time there is restriction there is heat, when it gets hot, even more restriction, all created more heat at the battery and less life.
That said, I am sure that BD designed using a proper cable for their systems based on a certain parameter such as something along 2 15 sec cranking cycles before getting too hot. Have a bigger cable would help, especially if having a higher load.
Just thinkk of how hot a cheap set pair of jumper cables of low AWG can get compared to the good ole ones made out of 00 AWG welding cable with proper clamps.
If one does change though, make sure that the proper connectors are used for the bigger wire gauge.
Just my 2 cents.
