2012 Wake Pro 215, no start, no beeps

[jrannik]

i,

I have a 2012 WakePro 215 - second owner - when I try to start it absolutely nothing happens- no start, no beep, no response from instrument panel -

Here are my troubleshooting steps -

1. checked battery - 11.5 volts (is this not enough?)
2. bypassed electrical system by jumping the solenoid - result is that engine starts
3. checked all the fuses in the fusebox - all are good
4. inspected fusebox, reseated all fuses after cleaning fusebox for any possible corrosion - looks ok
5. checked continuity on wire leads on underside of fuse box to see if there was any break or corrosion - none found
6. inspected start button switch, DESS key post for corrosion or damage - none found
7. replaced 30 amp relay after visiting forums and seeing that suggestion - wow, a result! now when I press the start button, i can hear the new relay clicking, and briefly the display flashes on then goes off- but engine does not start.

What can I try next?

11.5V is not great, when you jump the solenoid, does it crank fast and start fine?

I put the battery on a trickle charger overnight, and low and behold, the dang thing starts! got 12.5 on the volt meter- so it looks like a combo of the 30 amp relay and the weak battery were the culprits. Thanks!

FYI, this is a state of charge - voltage graph, 11.5 v shows us a 40% state of charge of a new battery, with our small, low cranking amp, low ah batteries, battery voltage needs to check in around 12.5v as you have shown to supply necessary current for starting.
