solidFIX for the R/R and cold start "issues"

[solidONE]

After my last set of battery and regulator died I decided to upgrade.
Here it is:

Posing my bigassed batt. and R/R, supersize please!

Sick and tired of jump starting my bike...

Biggie sized wires replacing the fried noodles.


My solidFIX for the SV650 charging system.

Fabbing up a bigger batt. box out of aluminum. I'll post pics when it's done. Peace and stay in the left lane.

Instead of fitting a monster battery you could have gone with the Yuasa YTZ12 or 14, both of which will fit in a curvy with minimum modification (remove the fusebox retainer) and give a good cold cranking boost and higher capacity... I use the smaller of the 2, the YTZ-12S, it's 11ah and has a CCA of 210A, vs 9.5ah and 175A for the stocker. More than enough to start mine after digging it out of a snowdrift

That a CBR reg/rec?

That new R/R was off of a '05 GSXR1000. After I saw the size of that thing. It was no wonder why the SV unit tends to overload or malfunction.

Allong with my bigassed batt., I hope to have cured the "issues" my bike has been struggling with. Namely cold startup (partly a carb issue) and keeping a battery charge.

The battery I bought is quite a bit taller than the stock one, but is the same dimentions length and width wise. I may have been able to avoid having to build a battery box if I did have the GSXR rear shock res. in the way. I don't realy mind the extra work tho. Kinda wanted to make a new untertail/battery box anyways.

Certainly is a beast of a battery Do you know what the numbers are for it, cap and output?

The reg/rec looks to be exactly the same as the common Honda and Kwak one- maybe Suzuki's finally learning a lesson?

The battery I got from my local walmart. The ES14AHBS battery is Everstart's equivalent of Yuasa's YTX14AH-BS. Spec's are identical, but a little cheaper I think. Plus I got $9 back for my toasted stock battery. The CCA is @ 210 and 12 a/h. Just one size bigger than your YTZ12.

The new GSXR R/R's come with 7 wires. The 3 usual stator wires and 2 sets pos/neg leads. Not quite sure why that is a better design, but the wire connections have rubber grommets that seal off moisture. A new feature I believe. I only connected one set of the pos/neg leads and taped up the extra set. I still have to test the charging system to make sure I've wired it correctly.

Here's a sid by side shot of the batteries:

About 3 inches taller than the stock sized battery, so I shouldn't have too much trouble stashing it under the seat.

Yeah, I tried to google the battery part number and got nothing but people slating Walmart But, doesn't mean there's anything wrong with the battery. There's an almost-stock sized YTZ-14S, and a Varta equivalent, which would give you more or less the same numbers and be physically smaller, but it's pretty expensive- the YTZ12 is more expensive than the stock battery, and the 14 was about half as much again So they're a good option, but VERY expensive. I like cheap, myself...

Cheap or not, I'd bet you money that the reg/rec there is made by the same people who make the Honda and Kwak ones. Good news that, since they're very reliable.

Just tested the charging system with the new R/R and test fitted the new big batt. Getting strange readings with the new R/R. @ idle the batt lead voltage reads 13.5v, but @ 5000rpm it reads 12.5v I think I need to try a different combination of pos/neg wires to get the correct charge. Unless my stator is shot... Hate electrical problems...


If you can get the YTZ14 for less. You should get it next time you need a new one. Rated @ 230CCA and 11.2 a/h, should help wake any sleepy SV after cold winter hibernation. Even with my slightly taller battery (compaired to the YTZ14) You only need to add some spacers btween the subframe and undertail to get clearance. Believe it or not, i got it to fit without modification!

Really tight fit in there with the GSXR shock.

Just got to figure out where to put the fuse box.


If the shock res was not there I would have no problems. Not that it's difficult to relocate the fuse box... A good upgrade for any 1st gen riders who have battery problems.

I am amazed that fits

TBH, I've never had any need for more than the YTZ12- I've literally dug my bike out of a snowdrift and started it. But, maybe some day I'll wish I had the bigger one.

I'm just as surprised as you are. Pleasently surprised, might I add. I was just tossing it in there to check clearances and approxamate mesurements for the sheet aluminum batt. box. So now I can put off the undertail for a later date and concentrate on other mods I'm working on.

Again, if I had a remote reservoir like a elka or a stock shock I would have a easier swap job. But it still fits, so I'm happy

Went over the charging system with the multi-meter. Just as I feared, my stator is goners. No load voltages was good but the risistances were @ .9 ~ 1.0 ohms. Factory specs are .2 ~ .5 ohms. Kinda explains the "fried noodles" I had to replace.

Let this be a lesson for those that keep putting off replacing the R/R by charging the battery. You run your bike with a bad R/R as long as I did, you might be in for a expensive repair down the road.

Now i think about it ... maybe this is my cue to start my carb to FI conversion... I already got a TB assembly here collecting dust.
