Won't Start - Single Click when key is turned over

[nathanfromal]

Hello,
I have a 2007 Tahoe Q6 with a V6 MerCruiser that I think is having battery or solenoid problems. I had the dealer replace the solenoid in the 2nd season and I have never replaced the battery. I am currently getting close to the end of the thrid season owning this brand new boat.

Here is exactly what played out at the dock:

1) I did not prime the throttle before cranking.
2) I turned the key over and the engine started trying to crank but I could quickly hear the battery dying, so I immediately turned the key back off. Yes, it was that sound you hate to hear!!!
3) I sat for about 10 seconds and turned the key again - only a single "click". The engine did not turn over this time.
4) I then repeated this key turning about 7 times in succession and only a single click with each turn of the key.
5) The guys at the dock brought over a small battery jump box which pushed the volts up over 12v, same single clicking. I also tried this with priming the throttle 3-4 times.
6) While keeping the battery jump box on, we tapped the top of the solenoid with a screwdriver and tried again- same single clicking.
7) checked the fuses, they looked fine.
8) I removed all the battery cables and let sit for 5 minutes, put them back on and same single clicking.
9) There was also a red reset button above the solenoid which we tried.

I'm getting ready to just buy a new battery and solenoid to see if that will do it.

Thanks for any help,

Nate - Nashville.

Clean every connection grounds also. Charge battery check battery still good.

Check & clean the connections at the battery first.....
The slave solenoid doesn't draw anywhere near the amps as the starter does.....

Thanks for the comments guys, but the battery connections and wires look spotless. The slave solenoid is clicking (I can feel it over the plastic cap), so it may be working based on other Posts I've read. Maybe there just isn't enough juice feeding from the battery to turn it?

Thanks.

Unhook the battery and clean the connections on the starter.

Make sure you unhook the battery.

Grounds must be cleaned believe me.

Good luck!

And,... Both Ends of the wires,... Not Just the battery connections....
