Re: Raymarine Ev tiller low battery alarm

If your only running one bank of batteries it is not uncommon for the startermotor to cause electronic s to fail.

It could also be a very easy fix, disconnect batteries clean terminals with sandpaper , reconnect terminals

Re: Raymarine Ev tiller low battery alarm

I'm sorry you have an injury. I'm glad this helps you too Sardean! Thanks for the help. Cruisers forum is great! No one in the harbor has any idea about batteries.

Here is a photo of my batteries so you can see what we are looking at.

Re: Raymarine Ev tiller low battery alarm

I have a few ideas but need more info on your battery set up, do you have separate start and house batteries

Re: Raymarine Ev tiller low battery alarm

wiring all looks nice and clean, do the thick red wires go to a 1 - 2 - both - off switch

Just noticed the red terminal in rear left of photo has white corrosion this can cause problems.

Re: Raymarine Ev tiller low battery alarm

Just noticed another thing, your big black negative wires should be first on terminals followed by the smaller wires under the wing nut you must have a washer between wing nut and wires to stop them spinning and alows you to get them real tight

Re: Raymarine Ev tiller low battery alarm

Ok. I took them all off and sanded them and they are clean, and they do go to a one two both switch. but now they won't turn anything on! The engine won't start, I have no power, what could I have done?

Re: Raymarine Ev tiller low battery alarm

There are some simple improvements to be made that will solve some problems. Depending on "1 off 2 both switch" and can you tell me which wires in photo go to the electrical switch board

Re: Raymarine Ev tiller low battery alarm

This is not bad that nothing works it may help find problems. Just do one thing at a time then test.
Leave lights on so you can see results
1 re check wiring against the photo you took.
2 check fuses
3 check on off both switch hasnt stuffed up by roughly rotating 3 or 4 times in all positions( sometimes the contacts jam or get bad connections - uncommon though)
4 rattle and bump wiring 1 section at a time

Re: Raymarine Ev tiller low battery alarm

Only the three fat red ones that go up in the back. They go to my switch board which them has all the electronics wires going to it.

The other wires on the battery on the right
One black and one red for solar.
One yellow and one red for shore power charger
One black and one red for bilge pump
One red cable to 1-2-both


Left battery
Two black for bilge pumps
One yellow for shore power charger
One red cable to 1-2-both

The other red cable from 1-2-both goes to the engine

What did I do that now nothing works? I saw a spark when I was reattaching my red wires on the right battery. Is there a fuse for the circuit breaker or the 1-2-both? Now my engine won't start or anything. Nothing turns on. All I did was take them off and put them back on.

As a side note I have a free wire in here that isn't attached to anything.

What did I do?
One red for bilge pump
One red for shore power charger

Re: Raymarine Ev tiller low battery alarm

Now I know you have a 1 both 2 switch , I am going to suggest swapping round some wiring, but first get it working again, then let me know which wires go to engine and which wires go to electrical panel

BTW I have been an electrician for 30 years and have had marine electrical buisness for 15 years, and I very much beleive in KISS principle, so dont stress we will be able to fix this problem

Re: Raymarine Ev tiller low battery alarm

It is no problem to see a spark, how did you go with checking wiring against photo

Is it possible to get a photo of back of switchboard

Re: Raymarine Ev tiller low battery alarm

Ok, we will fix this.

I will leave the light switch on to see which wire causes the problem. This is probably why I was getting low power. I had a loose wire and I bumped it and it is totally disconnected now.

Which wires or fuses should I start with? Which could cause the whole panel to go out? Is there a main fuse for everything?

Thanks again for the help. It's a race against time. It's dark soon and I live on this thing!

Re: Raymarine Ev tiller low battery alarm

It sounds like loose wire not fuse
