Battery Tray, PA Speaker
Another simple project that takes lots of pictures to tell the tale of...
Tired of looking at the piece of baling wire that was "holding" the battery.
Here the battery is removed, revealing a ton of sand, dirt, and small rocks.
Dirt flushed off, some rust here...
Tray removed from Jeep, phosphoric acid removes the rust...
Most of it gone!
RustOleum "Red Lead" primer. Note little angle bracket to left.
I should have taken a picture before assembly - but here is another piece
of angle to illustrate. Angle bolted - and pop-riveted to tray.
Bottom view - threaded through, but I added a jam nut as well.
Here can be seen the hole I drilled in the "other side" (foreground) as
well as the added angle in the background. This will enable me to...
...install these hold downs in place of the stock "wedge". The plastic washers match my toes!
Under the battery tray lives a vacuum tank/reservoir. Under that was dirt and rocks!
Most vacuum tanks I've seen are spherical, not this one...
Back in place, even the hold down bolt for this had to be reworked.
Repainted tray back in Jeep.
Acid absorbant "Battery mat" trimmed to size.
Battery installed. I elected to use nyloks instead of the supplied wing nuts.
Not much else to say about this one - I didn't care that much for the (missing) bolt down wedge style battery retainer, so I tapped the "metric something" hole used therefor to a ¼"-20, and used that to bolt down the angle as shown. I ended up using nylok nuts as noted above as space was a bit tight on the backside, plus nyloks won't vibrate off. I also added the felt washers for the anti corrosion dope, but I ran out of dope, so need to get some more...
PA Speaker with "custom" mounting plate.
Mounts using the two openings in the hood brace - by clamping.
Difference in price for the CB with PA capability vs not was negligible, and this 50 watt PA horn was $7.10 from "Warrior Women", so might as well have one. That's the good news. The bad news is that the CB puts out something like 7 watts to PA, which is ridiculously underpowered for any use whatsoever. So I'll need to install an inline amp to boost the power, although it does work as is. Why don't CB radios that claim PA capability actually put out useable wattage to same?
The other facet of this installation was finding a place this PA horn would fit. It fits here, although clearances are around ½" pretty much all around the speaker except in the front. But half an inch is as good as a mile, and the plate I used to extend the speaker forward will make a great place to mount a small project box with the amp inside. I already have the amp, but need to wire it up and otherwise get it ready as it isn't a drop in solution.
This video was what I used to figure out that it actually fits, but barely! Don't miss the plumbing van that turned around in my driveway when I was testing the thing...
Read on for the next part!
A "Caution Fan" is standard equipment!
Just drove it to the Post Office!
All cleaned up...
... and looking pretty!
I don't usually back it in here...
... but I did today!
Reprised from previously, patched tire was on the spare carrier...
But now the "old" tire is back there.
Patched tire back on ground.
Marking paint worn off after literally 1 mile!
And after 20+ miles, protruding rubber is starting to wear down a bit.
