voltage

A freind of mine has my old Vmax 1988 vintage and had the old regulator pop . He got a replacment but the new one gets hot very quickly ? 4 mins after starting it gets hot almost too hot to touch? any body got any thoughts or sugestions. We tested the stator and voltages and all comes into spec...

93 VMax. I have been having some little hiccups lately with the bike and I think they have something to do with the charging system. When I check the voltage at the battery with the bike running I get all sorts of weird readings. At idle it's charging about 14V and when I rev it to about 3k...

I've been running a UFO LED tail/brake light on my bike for the last several months. I don't do much riding at night, but on the way home for a local bike night I was alerted that my tail light wasn't working (brake light still worked). I pulled the light and sent it back to Jon at UFO to take...

Just finished the low voltage mod.Cold battery 12.0 .She fired right up and at 1000 rpm I get 13.5 and at 2500 I get 14.6 .How bout them numbers ?,and I for got to hook up my second ground to the v ,max cover .I may wire up a volt meter so I can see how its running all the time.They have nice...

This is one topic that comes up again, and again, and again, I'm pretty sure it's even surpassed the "which oil is best" threads in post count. Every time it comes up, there's lots of good info, until it slips back a few pages and the question gets asked again by another new member. There's a...

Ok, so in a nutshell what is the charging voltage at the battery supposed to be after the crimp fix, and idleing at 1000 rpms, without the fan running , mine is 12.7 then with fan on 12.3 / 12.5 but the bike runs funny at the lower voltage, whats the cheapest easiest way to inclease voltage, its...

Just wonderin what y'all think: Standing still (about 2 days after last ride): 13.03v Ignition on before starting: 12.34 Drop while starting: 10.3 Idling after a 20 minute ride: 13.99 4k RPM: 13.99 The fact that it is higher idling after the ride than it was when I started...

Whats up v max heads?? Im new on the forum and I heard this was a good site to talk about possible upgrades for the v max? So does any body know where I can get a better voltage regulator that will work for the v max? the stock one just does not put out enough volts. anybody?

Voltage Regulator Issue / Fix - MUST READ! Might be a good "sticky." I just replaced my battery (VERY bad shape), voltage regulator, and stator. After all that I was showing 13.5 volts at about 1,200 RPM, but then any higher RPM would drop it down to 12.3. I contacted the person I bought the...

What should the voltage read from the stator with engine running? Idle 2000rpm 5000rpm ???

my 1985 vmax has gone though 2 R/R and 2 stator and now it has burned up my new R/R i just put in. and my output on the stator said 120 volts and i don't how much my stator should really be putting out i have heard it should be only being putting 60 to 80 volt so i need some help does anybody...

OK, this is a question for a friend. Its not about a Vmax. Its about a ...gulp......sportster. He has an '05 883c. We put a 1250 big bore kit on it this winter. Runs fine. His trouble is that he has just put the 3rd battery in the bike. Its only 4 years old! I told him to try out Lankee's...

Hi all once again. A strange problem has surfaced with my 95 max recently and I believe it is a regulator/rectifier issue but am not too confident with checking things out using the fault finder. Electrical has never been my cup of tea and I don't want to burn something out. :ummm: So can...

Hello all. what should the charging voltage be when the bike is at tick over and when reved to 5000 revs should the charging rate rise? my bike stays at 13.6 volts at tick over and the same when the engine is off. Thanks Crano:biglaugh:

Bike died when running WOT (doing nothing I or the guy who lost wish to put in writing in a public forum). Bike was completely dead and it turned out that the voltage regulator had died, gone short circuit and blew the main fuse. Prior to this total failure I have been experiencing...

Is there a chart of specified voltage output at various RPM? Does anyone here have a Voltmeter gauge mounted? On my last couple of monthly checks, I added distilled water to the battery. Granted it's been darned hot here in Las Vegas this summer. In the past, I have used a multimeter across...

My '85 has a piss poor charging system. I tried the crimp fix, soldering the 3 stator wires to the r/r unit, and running a ground wire from the unit to the battery. I just finished wiring the positive wire from the r/r directly to the battery, too. Start things up cold. (Battery reads...

First post here. Just got my first Max last week. It is a 86. Ive wanted one of these since 85 when they first came out, and finally got one. Bike runs fine and starts every time, but... lights dim when motor is revved so I checked the voltage at the battery. When it is idling it will be...
