The thread was from May or June of 2016. Good write up and instructions.

That sounds like exactly what we need, thanks for sharing WL882 you always seem to point me in the correct direction. Did you have a link to that write up or am I missing it there somewhere?

Sorry found it, first searches were not working.

This sounded so promising... however I have a 97 boat with single battery and it seems that the problem still exists during the cranking phase of restarting the engine... If that is not the case please confirm. I may be adding a lighted toggle and wiring direct to battery and bypassing the ignition completely.

Perfect. That is the thread. I put that thing on a while back. Works great. That guy's instructions are superior by far to the ones that come with the product. Best luck.

If you still have the problem with the relay with the one battery, wiring it directly to the battery won't help. The issue is the voltage is dropping too much while cranking the engine and the only fix will be to add another battery.

Hmm Ok - let me sleep on this one for a bit, appreciate the input. Will certainly be considering this mod.

Was able to find the wires from ACC-2 switch and run over to the new usb outlet. Looks good, I think anyways... and functions perfect. It reads 12.5V and If I test at battery it states 12.64V so it is only off .14V that does not seem to bad to me. I do have the 2 small mounting holes from the old power socket to figure out how to fill, any suggestions? Otherwise better than inserting a usb dongle.

I like it.

The other relay is an easy install. The most tedious part is setting the delay time. Not hard, just takes a few tries to get the settings to go in properly.

Thanks

If I read correctly... I can make all connections associated with the tr-7 relay right at the radio harness location? If so I am happy to say I just ordered a tr-7 relay!

10-4

The instructions that guy wrote are spot on so take them at face value. I was leery of one step (just didn't register with me at first) but the instructions he wrote will get you there.

Also you won't use all of the wires (seems odd) but that is the skinny.

best on the install.
