    What can I do to get more voltage at low RPMs?

    Ran into a low battery voltage not too long ago. Reason; putting around, using the Vmax like a scooter, and not like God intended. I honestly see myself staying more local and off the HWY, so low rpms are what I am envisioning in the future. So I was wondering if there is an option to allow...

    Fuel Pump voltage question

    Does the Fuel pump Voltage on my 1985 V-Max supposed to drop to zero after V-Boost is done cycling? What signals it back on? Mine does Also with the Fuel pump electrically connected the V-Boost cycles VERY slowly on Key on, Unplug the fuel pump and it goes normally My Max started acting...

    Voltage?

    Hey every one I know I could have looked around a little more than I did and answered my question. But i figured a quick question would yield a quick answer. What voltage should my battery have not started? And at idle? Happy cinco de mayo! Don't worry I'm not riding tonight Sent from my...

    Updating my 2005

    Hi I'm recently new to maxdom, however been riding for 50 years. A guy dropped off a 85 with Supertrapps at my shop for charging issues and I fell in love, 2 weeks later there is a lovely 2005 anniversary edition with 10k miles in my garage. Yes it had the same problems/issues that all the rest...

    Voltage indicator

    I think I know the answer to this, but I figured I would ask. I hooked up a voltage meter to the power lead on the tach, and the ground, it's reading a volt below what I got on the battery, but I an fine with that. When I started the bike. The reading didn't change. I think when I last did...

    WEIRD stator voltage

    hey guys quick question. I tested the three stator wires tonight doing the 3 wire combos using ac volts and at idle it read 11 across all 3 and would not go higher in fact when I revved the throttle to around 4k the reading actually went down to around 8.5 any thoughts I have been having a...

    Fuel Pump issue

    I have a 85 vmax and it has been sitting for 2 years. i pulled off the carbs and cleaned them and then i noticed alot of water in the fuel tank. i removed that and then when i turned the key on to see if the fuel pump was working it spit out water and rust. i kept turning off and on until the...

    Typical Voltage drop while cranking

    I am discovering the quirks of my newly acquired '85. I recently experience the slow crank when hot. I suspect the battery but will also check the crimp. My levels are: Ignition off - 12.4v Ignition on - 11.6 Cranking - 9.5 I suspect 9.5 is too low as is 11.6 with the key on. I'll...

    Losing voltage

    Since I was having charging issues I replaced my R/R with a newer version from Sean and everything looks much better (14 volt across terminals @ 2K rpm). I wanted to add a voltage meter to be able to better keep an eye on everything and started looking for a wire to tap into. I purchase one of...

    Voltage drop when accelerating

    Voltage drop when accelerating I'm about to start trouble-shooting my electrical system. I'm going to follow RaWarrior's thread to try to resolve my issues. http://www.vmaxforum.net/showthread.php?t=19108 Bike usually starts right up without issue 1 time (when on float charger)...

    Voltage loss in brake wire when light is hooked up.

    Hi All, I have a 88 Vmax, i have a very strange problem with the brake light wire. It had got layed down previously and upon putting the bike back together from mostly minor damage I got new LED dual running and Brake lights. But when i hook them up which i have done on a few other bike with...

    measuring stator voltage

    I am new. Great site, been doing alot of reading. My question is about measuring the AC voltage at the stator. I have read that you can measure this voltage by measuring across 2 white wires, and also that you can measure it by the red lead on a white wire, and the black lead on ground. If...

    Voltage Regulator Removal??? WTF???

    uh...noob here. I have a new battery but the charging rate almost non existent. Multi meter shows this. I looked for the voltage regulator "behind the left rear passenger peg. It's there, I see three white wires and one red wire and they go up to where somebody cut out the connector and...

    Ac voltage from stator

    questions is when checking the voltage from the stator (3 white wires) do you test wire to wire? and what should the output A/C voltage be on each leg? Anyone know this? I though I read something here a while back but I cant seem to find it now. Any info or a link to what Im looking for would be...

    Low voltage causing V-boost failure?

    Since I got my bike back from the shop where it spent a month or so being overhauled, the V-boost kick at 6k rpm is gone. Everything is hooked proprely and seams to be working OK appart from one thing. Checking the voltage at the battery, I get a good reading. I start the engine and the...

    voltage regulator

    Hey guys, I have a 86 max. The V/R (voltage regulator) went out on my way home from work Monday, of course on I-95. I had replaced it last year with a new one from Ricks motorsports regulators. It wasn't the fined style regulator . My question is, what year regulators are compatible with my...

    Poor Idle Continues (Voltage Problems?)

    I have been having some issues with my bike over the past few weeks and posted up in a couple of threads about my issues. After getting a bunch of advice from many great people I tested my stator and r/r and didn't find any problems. I replaced my battery but still seem to be having the same...

    charging voltage

    This all started when my max would'nt start when warm a couple of times, I took the battery out and charged it overnight, disconected the charger next morn and left the battery untill I returned from work about 8-9hrs later. The battery voltage then was 12.4 (thought is should have been higher...

    more voltage, more power

    hey, I have noticed something really weird and I don't know if it's related to the engine being cool or if it's the battery charge. I would leave the bike connected to an external charger overnight and start it in the morning and after some time when it's warmed up I would run it hard and it...
