Title: I'm no electrician .........
Post by: beerjet on June 26, 2008, 02:30:18 PM
But my battery is hooked up the same it's always been . I went to tighten the wing nut on the negative side and burned the fukin piss outta my fingers  :mad:

The boat has been sitting without being ran for a couple of weeks so I went in there to fire it up and of course it didnt fire after cranking it a few times . Thats when I decided to tighten the wing nuts on the batteries . This fukin thing is always taking steps backwards  :mad: I dont know the first thing about electrical and it seems that electrical is the only thing that gives me problems on that fukin boat  :banghead:

Thats common when you make the battery work harder than it should........ Just throw a charge on it and fire it up ;D

My buddy blew his motor last summer. After rebuilding his 460, his blue top cranked the motor just 3 weeks ago without being on a charger for 1 year.

i will take that blue top off your hands for ya. but i would check your grounds on your engine block or where ever you have them. that always causes some weird shit to happen if you are not getting a good ground. check your batter selector and all your grounds and make sure the connections are clean and tight.

see if that works.

i say shizz can that boat and give it to me , i seem to be collecting boats.....(probably a ground problem)

Post by: FORKEDUP on June 26, 2008, 03:23:40 PM
I would have to agree with aqua, if you have a bad ground it will create extra resistance and cause the cable to get hot, if your starter is going bad it can also draw to much ampers and create the same type of problem, i would start with the grounds, good clean tight connections

 Stop tightening the dirty connection and take it apart and clean it  :screwy:.  The hot connection (The one that burned your little fingers) is the dirty one.   Also if you always have a starting problem after sitting, check the boat by putting an amp meter between the bat and the + cable, you might have something drawing power even when the key is off  :-\ .

Hi Beerjet
i`m an electrician and it sounds like you are drawing current. do like Propless suggests and put a meter on the battery. do you have a radio at all. you might have it drawing power just sitting. make sure all your  connections are tight. not just on your battery. a loose wire can and will pull some juice from the battery. and check all your grounds on everything. sometimes a loose ground will pull power. good luck.

If I read this right, you cranked it didn't work, so you then tried to tighten the connection.

The connection is dirty or the wire is too small, either one causes resistance and therefore creates heat when current is put through it.

Clean it...

I do have some loose ends as well . The entire boat is getting rewired because of this issue I always have . Looks like sooner than later .  :D

 i`m not sure who originally posted this but i do remember it was someone from this site. so for who ever it was the credit goes to them. i hope this will help you out.

As a wiring technician/enthusiast, I have always been a stickler of sticking to the color code of whatever I'm wiring. Some guys don't really care about the color code...they just want the damn thing to work. However, I prefer the color code for a few reasons:

1) The wiring job looks like a professional did it
2) Easier troubleshooting for you
3) When you go to sell the boat, everything is done to a standard to allow the new owner to troubleshoot easier

So here I will post the marine standard electrical color code for jet boats:

Black - All grounds
Red - Constant hot (all wires that have 12 volts on them regardless of key switch position, "BAT" terminal on key switch)
Purple - Hot In Run (switched hot, controlled by key switch i.e. ignition, gauges, etc, "IGN" terminal on key switch)
White - Hot In Start (runs the starter bendix or aux solenoid)
Light Blue - Oil Pressure Sender; "S" terminal on Oil Pressure gauge
Light Brown or Tan - Water Temperature Sender; "S" terminal on Water Temperature gauge
Grey - Tachometer signal from ignition; "S" terminal on Tachometer
Orange - Bilge Pump hot from switch to pump
Pink - Bilge Blower hot from switch to blower
White/Red - Fuel level sender; "S" terminal on Fuel Level gauge
Yellow - Lights from switch to lights

Optima batteries have never impressed me, unfortunately the company I work for owns them, these batteries don't have a lot of "reserve" power, but they have a buttload of amps available at first (low resistance), they are also a pain in the ass to charge because the require either a "trickle" charger or a charger designed for this type of battery, if you disconnect the battery when the boat is not in use the battery should stay charged fully for months.

A friend of mine works at Auto Zone,  he told me to NEVER buy an Optima battery.
They have more trouble with them than the other brands combined.  His words, JUNK

I never used one that was his word from experiance selling them.  He said they had to many (dead returns)  of nearly new batteries.

Now there is a man who knows what he is talking about. JUNK is right. My buddy had one in his Mustang and it melted. There was nothing wrong with the wiring. It really did melt. I would never buy an optima.

ps- 2Sav wiring the boat is easy. I got all my tinned wire and terminal ends from McMaster-Carr. I also wired in a scotsche fuse panel under the dash. Do a search on this site on wiring and I thing there are posts and wire diagrams as well.

my red top in 3yrs old, sat on the shelf in the garage for 2yrs while the boat was apart, still works great.  i think, i did start having starter issues in parker that i need to check  ???

SHIZZZ can those optimas and go with an odyssey or kenitic, more power and smaller/ light weight

Post by: KonaCole on June 27, 2008, 09:21:31 AM
I have a friend that ran an optima in his race car and said they were junk because it gave him nothing but trouble.  We put a full set in my dads bass boat and they lasted 1 year.  He runs die hard marine and gets about 3 years out of those.  I have two everstarts in the Kona, but it is too soon to comment on them
Title: Re: I'm no electrician .........
Post by: speedymopars on June 27, 2008, 09:26:42 AM
I ran the original optimas in all my cars. The one in my van is 15 years old, the thing can sit for 6 months and it still starts without touching a charger.

The new "improved" optimas, well, thank god there is a 3 year unconditional replacement garentee - I seem to burn them up every two years.

Something screwed up, I don't know if they outsourced it, sold the company, or got a new manament team in there - but the old ain't the new....

I just pulled the old battery try out of my boat and had one made/ polished. Got a Optima blue top and a new billet battery box, Batt  sat on the floor for a year, it just dont have the balls the old battery had. Now only the Optima will fit in the boat. Called Optima, got a new one on the way. Today is my B-day, so I'm hopin it comes today. Plus they told me to take it to Pep Boys to have it checked and to leave it there for proper disposal so I kept it. Maybe it will come up w/ a few cycles, dead charged, dead etc.
