I am going to use a relay to power my starter solenoid. I could use a 60 amp bosch style relay or the bigger ford type. If I use the ford style (that is called a solenoid), I see some that are rated at 15 amps.

200 amps would be needed, if used to power the starter with a jumper to the starter solenoid and that 200 amps would pass through the ford style relay. Even the starter solenoid could draw 30 amps when hot if wired only to the starter solenoid.

So, what does the amp rating ( 15 amps ) on these ford style relays ( solenoid ) mean? Do I need to find one with a 200-250 amp rating?
