As I mentioned last time, Crawler is having a laugh at my expense.
I have confirmed that the G424 Alternator is in-op, it had to happen sooner or later I guess. Least it could have done was give a little fair warning....Like so...
|If only it had been that forthcoming....sigh.|
So I did what any reasonable person would do ( ...well...a REASONABLE person might not have bought a used Ural... but that is a blog entry of it's own.)
I put on my WWID hat and got to scheming.
|It ain't pretty...but it'll hold. I think.|
3 words.... Total Loss System.
3 more words....No More Bomb.
What is a Total Loss System?
Well it goes like this: The rig needs more than 10.5 volts at 8 Amp/Hours to run.
That means on average, with the stock lighting and coil/ignition module both engaged the system draws around 8 amps of power. The G424...when it worked...put out a whopping 11 amps. Meaning that the rig was draining 93% or so of the alternator output...leaving little more than a maintenance or 'float' charge for the battery. Basically enough to put back what it takes to kick start the bike....barely.
A standard motorcycle battery has a rating of 10 or 12 Amp/Hours good for about 1.5 hours of run time without an alternator. Which translates into about 50 miles ...sucks huh? Yes it does...see last entry.
However, for about the price of a good motorcycle battery you can acquire a Deep Cycle Battery with a 115 Amp/Hour rating good for about 14 hours of demand . Which translates into about a 500 mile range on paper. In real world estimates...I can expect 250 miles before I drain the battery low enough to damage the cells. More than enough for commuting and scooting around with The Boy. The downside is a deep cycle battery is BIG. Around 14 inches long, 10 inches high and weighing 35 lbs. big. Luckily I have a little bit of extras space.
As I mentioned last time...cost and time are a factor in the decision.
Here's a lil visual aid.
- Replace 424 Alternator with another 424.
- Cost: ~$300
- Shipping time from Ukraine- 4 to 6 weeks
- Likely to fail again.
- Replace 424 Alternator with Denso unit
- Cost ~$500
- Shipping time from Germany- 2 to 4 weeks.
- Cat's meow...outlast the engine most likely.
- Replace 424 Alternator with Total Loss System
- Cost~ $80
- Shipping time- NADA
- Limited range(but within projected use profile)
As you can see, while Total Loss is less than perfect, it suits my needs for now and is a damn sight easier on my wallet than any other option. Additionally it smacks of one of the things I love...creative problem solving. I am redoing the complete wiring loom [second time], fabricating a solo seat mount and rear fender cargo rack(not to mention the super sexy plug pictured above) mostly with crap that was in my basement leftover from other projects or found/scrounged supplies.
Yeah, so it's a 'Rat Bike' solution. Maybe it's even a lil hillbilly.
But it's good practice for the Apocalypse.
