2000 Yukon XL intermittent starting problem

[The Real Scotsman]

Our Yukon XL will occasionally not start. It is not a battery or fuel problem but when the ignition is turned there is no crank and the dashboard lights dim. After waiting awhile it will then start. Any ideas?

The fact that the lights dim indicate that power is getting to the starter. Either there is a bad battery cable or the starter itself is going bad.

I would start by cleaning the battery cables (at both ends) and replace the cable(s) if they look bad.
