I've measured my parasitic draw at 33ma. I keep a battery tender on it when not in use. Dave

Mine measures 37 ma. I keep a battery tender on it at all times when not being driven. A parasitic draw in the 30-60 ma range will bring a battery to the 80% state of charge within days. The battery plates sulfate at that point. The battery will lose capacity and ability to store a charge. You...

You want to measure the parasitic draw on the battery when it is resting. Mine is 37ma. If you don't have a meter I am sure there is a local member that could help out. These cars are power hogs compared to most other cars. The other problem that has now been introduced was jumping the car and...

Non-ethanol fuel is available with a little looking. Check out Pure-gas.org So far it looks like 7-9% improvement in fuel mileage. Dave

NSXtasy: That particular trip was from Seattle To Mountain Home, ID, on the way to SLC. The mileage was 32.x mpg. I had ~.75 gallon left. My all time high mileage was 33.59 over a several hundred mile trip. The numbers are impressive considering the car is an automatic. One of the big keys to...

^ absolutely correct. Thank you. Dave

The NSX seats are the most comfortable seats I have ever sat in. I have driven Seattle To Salt Lake City with only one stop four times. Longest leg was 545 miles in one sitting with no back complaints. I have a two-level fusion at L4-L5, L5-S1. Dave

For another reference I have a 37ma parasitic draw on mine. Dave

If there is a load on the alternator disconnecting the battery will spike the alternator. It can go up to about 60 volts for an instant. The diodes in the rectifier are probably 20 volt diodes. You will blow out a diode. There is a feedback loop in the alternator/regulator that identifies the...

I drove the NSX to Salt Lake this summer. On the way down a good place to stay is the La Quinta at exit 29 in Idaho. You miss the Boise mess. Dave

By dressing the sliprings I mean to take some emery cloth and holding it on the sliprings as you rotate the rotor. Finish off with 2000 grit. The brush assembly comes complete like yours. If you look carefully at both sides of the brush holder one side is flat and the other had a small step in...

I rebuild these alternators for the Acura Legend forum members. I have the pieces you need if you can't find them locally. I would suggest you use Denso bearings. Make sure you dress the slip-rings. You will need a three-jaw puller to get the rear bearing off. Dave

I am very happy with the Battery Tender Plus I recently bought. In the constant voltage stage it holds 14.6 volts in a cool Seattle climate. It will drop down to a safe float mode after the battery is completely charged. Dave

I have a 150 with an inop autopilot and an ADF. Dave

It's normal to see a small spark when you hook up the battery cable. You are charging a cap and energizing some systems temporarily. After a few seconds the system draw should go down to the normal ~35ma parasitic draw. You could easily measure the draw with a multimeter. The trick is to have...
