UPDATE: I got this fixed up -- turned out I needed to replace the display.

So my RadRunner plus won't turn on, possibly because it was left out in the rain for a day. I've already done the following to try to fix/diagnose:

- Tested the battery

- Checked and secure all accessible connections (I wasn't able to pull the wiring harness cable until the connector is out of the downtube, so couldn't check that one.)

- Replaced battery fuses

Rad Support says:

QuoteIf you have already performed the connection check my recommendation would be to start by replacing the main power drive components, we can start with one at a time or replace all 3 at once. Here's a break down of the cost for each part:

LCD Display $100
Wiring Harness $30
Battery Tray $30

Any ideas on how to bring my bike back to life, or what the most likely culprit is?
