The plastic housing pops off after a few weeks of heating and cooling expansion and contraction. You have to glue it on to keep it on. It is NOT water proof unless you seal it on the back BEFORE attaching it to your brake fluid reservoir. Other than the above it does work, though in bright sunlight it is useless.

Nothing wrong with it, works great.


Purchasing this unit was one of the smartest things I've purchased for my bike.It was very easy to install and keeps me advised as to what my charging system is going on my bike.


works good


overall good product had to notch the inner and outer plastic to surface mount. kina cheaply made but ok see how it holds up it is bright, had to put it outa sight so not to distract.


This is the perfect fit for my bike cause mine didn't have a gauge it's a 1991 fatboy. This product saved me just last week when it showed that I was overcharging putting 19 amps to my battery and not being to far from the house I went home. I had just put a new battery in my bike a week before and if I wouldn't of not had this product on my bike I would for blew up my new battery. Come to find out the problem was my regulator. I bought a new regulator put it on and I am good to go. Now I can go to Sturgis this year knowing that my charging system is fine.


Works great. Wanted to make sure everything was working properly after replacing Stator and regulator and battery. Was told the biggest reason for this failure was battery got weak. I believe this little monitor which looks great, will be a cure for every having to replace stator again.


Works perfectly.


A simple to install and very handy gauge works great!!!!


Extremely easy to install,Works like a charm,Looks great.Shipping was fast.Always a pleasure doing business with J&P Cycles.Mike Palm Harbor Fl.


I've been using this handy little batt gauge on my present and previous bikes. It's easy to install and easy to tell what your stator and battery is doing.


Easy to install


LED is bright, differnt color to tell the strength of Battery hence easy to read


it works very well.looks like it was made for the job.


Very easy intallation. I fryed my rectifier, stator wires, adn battery, so I wanted a quick look battery tender to install on my 1100 - great little product. I put a little electrolite gel on the back to help with water proofing.


This is really great so not getting caught short with a low battery out on my own. I know what my battery is doing and if it is charging


It's a good little gauge to monitor the charging system. I did put a small bead of silcone around the bottom lip to prevent water getting inside the unit. But the sticky tape seems to be holding well. Easy to hook up to your electrical system is a plus. The small size is easy to work with also. All in all a goood buy!


great product,and fast shipping.


Works as expected. Nice to have.


Battery gauge works great. The printing could be better on the item.


I returned the gauge after discovering that I didn't need it as my electra glide already had one!


doesn't stand up to Oregons weather


Great product! Nice lighting sequence to see during startup/checkout.


Small, powerful and nice design. I put it behind the engine, on the battery box and it lights up my engine! Nice device for the price.


99% of the time I am never disappointed with Kuryakyn products very good quality


The first one purchased worked just fine; but failed after a heavy rain. When I removed it I found the base to be loose. I replaced it with another, ran a bead of silicone around the base and so far this one has not failed. Very happy with the operation.


Bright leds.My 14 was rubbed off and with a slight scratch.it is not that bad to really notice.Works great.


great product. 2 things to be aware of: 1. The LED's are BRIGHT! I decided to mount more out of sight because of this. I have mounted to top side of Coil Cover so I periodically need to look down to monitor - w hich is OK. 2. the LED strength function is directly related to where you tap off the 12 V signal. If you don't tap off to a high voltage (eg close to 12v) you will normally only see 1 green LED instead of 2. That is OK - as long as you understand that that is still a good reading.

Small enough to fit nicely in a gap in my bike's gauge pod. Paid for itself the first day I had it installed as a few miles out the R/R started allowing too-high voltage through.


This gauge is a really good thing to have. It's reasonably easy to install (you do have to figure out where an "always hot when the bike is on" wire is in your headlight bucket). It also looks good on the bike (chrome naturally) and isn't gaudy or obtrusive. I refer to it often to make sure the electrical system is OK. This is especially true when running extra lights or other electrical add-ons.


I like the product. It works very good. I give it a 4 star because it is small. I expected the product to be larger than it was.


Neat little product that gives you your dollar's worth. The only "complaint" is that it's awfully bright and the "dimmer" feature stopped working after just a few hours of my Harley's vibes and shakes. In fact, it's so bright it can actually distract your eyes from the road at night if you let it. I will say that I did get used to it and it does give an accurate voltage reading, which is really what it's meant to do, right?


Nice to see the battery status with all the electrical add-ons. Just a quick glance and you know where you stand..day or night.


This is a great item for older motorcycles. It works great, and was a great buy. Thank You


VERY pleased with the product and ease of installation.


80% of parts I have put on my bike came from J&P Cycles. I am always satified with the parts and delivery. I recomend them to all my friends.


Was just what I expected. Easy to install and works like a champ. Thank you J&P
