Project Turtle: 1993 Toyota Tercel/56K=FAIL - Page 32

Started working on the fan bay today, but I can't get the plastic welding to hold like it needs to. As much as I hate to, I think I'm gonna use ABS cement(God, that stuff stinks... literally). Hopefully that will hold it together. I have managed to get the motorcycle battery to hold a charge. It just needed more acid in it. What it had must have spilled out. (I had it in a moped, and I took a quick turn onto gravel, and bit it...

)

You may want to see if you can locate the motorcycle battery under the hood, because it produces fumes, and they're caustic. The underhood area is very well vented, even when stopped, because the radiator requires it; neither the cabin nor the trunk are vented that well.

In my car, there's still some space available in the area in front of the left wheel well. I'd have located a second battery there if I hadn't used a sealed lead acid system.

The wiring is the same no matter where you put it..

OMG whats up with you driving off the road, lol. Also, what I would do is use Popsicle sticks to act as a reenforcement to make it stronger. I am guessing there is to big of a gap so the plastic is sagging and or falling off?

The wiring is exactly the same.

OMG, please make sure you put that battery in a safe place. You know dealing with electrical is so scary. Maybe thats why I am the only one that thinks its a bad idea.

Tidder: that was two years ago, I couldn't get it to start after that, so I gave it to a friend who works on motorcycles. I think he ended up parting it out.

HiJack: I'll try that. And I'm gonna go look at my engine bay right now and see if I have the space there.

I do have space, next to the other battery even. I just need to finish charging this one and test how long it'll run

Since I added a cold air intake awhile back, I've been meaning to remove the factory air filter housing. Today gave me a reason to do just that. I removed the air filter housing, and what'dya know? Just enough room for the motorcycle battery(or the two scooter batteries, even). Two trips to AutoZone later, I had everything wired up and ready to test. Preliminary testing went well, but afterwards, my OPUS started acting up. All the wires were attached the same way they were during testing, but the light was blinking twice. I shorted the pins manually, and everything powered up, but I still haven't managed to get the OPUS to power everything on on it's own. Any suggestions? (And yes, I've flipped the plug on the pins on the MoBo...)

I wonder if the auxiliary battery Voltage is too low to get the Opus to turn on. Have you measured its output Voltage at full charge?

Looking good . . .

With the car running, both batteries are at 14VDC. With the car off, the main battery is at around 13VDC and the AUX is at 12.7VDC. The OPUS light blinks twice either way; car running or not.

Change the voltage down to 11.7 on the OPUS by adjusting the jumper. I cant recall the number, but I think it may be posistion 4 or 5 or 7.... I would check the PDF.

freeflashstuff · 07-29-2009, 04:18 PM

I lost all the jumpers... They're all zeroed out, so shutdown delay=10 seconds and shutdown voltage=8.5VDC.

I got my fan box finished today. The ABS cement held what it needed to, so I finished the smaller parts with plastic welding. Pix follow:

Inside:

Finishing the cold air intake is my next step. I still wish I knew what my OPUS's problem is... It still blinks twice...

I think that is perfect. I didn't realize the part was so deep though. You still may want to put a small plastic divider in the middle of the fans. Underneath, maybe about 3 inches. That will create even circulation.

Well, I'm going to Dallas tomorrow morning, so I'll try to do that today. I need to find something to cannibalize plastic from so I can make that divider. I used all of what I cut off of this for the plastic welding and the center piece. A CD case would work, wouldn't it?

You can actually use a piece of wood, if anything. No one will see that part.
