Re: What did you do to your Suburban Today?

How to install a starter in only 6 days...

Wow, what a task that ended up being. I was able to physically install the starter last Monday night, but it took the rest of the week to get it right, specifically the wiring. I "upgraded" to the newer gear ratio starter which costs more but is smaller, lighter, less current and spins faster. I wasn't aware they are more sensitive to voltage. I rewired the electric fans to be off during start (when hot), I rewired the bat + & - increasing to 2awg wire. After all that, I still had to rewire the solenoid wire to go thru a relay. This gets the starter & solenoid voltage up over 11V...finally...and cranky very quick. I still have to reinstall the dust cover.

I also did a lot of timing gyrations thinking the initial timing was loading the engine too much which in turn was slowing the crank. In doing this, I did see the harmonic balancer seal coming out and a new plug wire gone from an exhaust manifold crack...my next week's entry in this thread.
