Default Help needed-Wiring Problem?

Hello, I bought a 1994 Lowe 2220 Deck Boat a week ago. Had it on water yesterday and all was fine, however, the radio quit working. Today I had 5 kids waiting on me to take them boating and I crawled under the dash to see if there were loose wires. I checked connections and could not find anything. When I crawled back out and checked I had lost all accessories, no horn, no lights, no bilge pump, nada. The boat has a starting battery and a battery for the accessories. The motor will turn over. When I checked circuit, I had no power at power line coming in from accessory battery, but did when checked at the battery.
Here's where I get stumped. I ran a new wire up to the dash, I grounded the circuit tester on a aluminum bracket on the dash , nothing, (the wire to the key lights up the tester when grounded to this bracket though.) I took the wire back to the battery and it lit up the tester. I seem to be missing a ground somewhere in the circuit? The wires from the Accessory battery are inaccessible in the Hull, but I think the problem is a connection. I worked at it for over 10 hours today with no success and very disappointed kids. I would greatly appreciate any suggestions and advice anyone might have.
Thanks!

Check and make sure the connections are clean and tight, are there any switches? You might have to replace the cable, I don't think you can test continuity with a test light, do you have a meter? Makes things a lot easier even if it's only a 20 dollar one.

You seem to be confusing your boat with a car. All boat wiring has a negative return that is an actual wire. Nothing is "grounded" to metal parts of the boat.

Before you start running new wires and crawling underneath the dash, I suggest learning how boats are wired. There are several books on the subject. Here is one:



http://www.amazon.com/12-Volt-Bible-...4533725&sr=8-4

Note that boats use tinned "marine" wire, not wire from the homecenter or auto parts store. Same for connectors, etc.

Seriously, get the book and read it untill you understand it before you start working on your boat's wiring. If you read the book and don't understand it, call in a pro. Those kids will be really upset with you if they end up drifting down the river because of faulty boat wiring.
