I have a Ruud air handler with a 3/4 HP motor (model UBH J25 J11 SUZA 1).

Neither the compressor nor the air handler will turn on.  Just wanted some basic guidance troubleshooting the electrical system:

-is there an easy way to bypass the thermostat by touching 2 of the lead wires together?  If so, what colors?  Here is a pic of the thermostat:  https://drive.google.com/file/d/0B4i04vbfPxdjRlJPdnFJMWRUSVE/view?usp=sharing

-what are good steps to take to troubleshoot the system for electrical issues if the thermostat is not the issue?  Here is the air handler, if that's helpful:  https://drive.google.com/file/d/0B4i04vbfPxdjdF9ETWJCd1JZQXM/view?usp=sharing

Thanks.
