Hey, haven't been on here in a while, but i need this forums infinite wisdom again :P. Would it be possible for me to install a second alternator in my 1994 Honda Accord LX? I have a fairly large audio system and the car isn't powerful enough.
The only question is: how do you install one easily? This article. discusses a technique to mount a second alternator on almost any. And it’s worth noting that the process can.
Yanmar engine? Before we start the project check your engine model. Do you have. a Yanmar? If so you may be able to purchase a complete second. Yachtwork. Yachtwork. Yanmar highouput marine alternator. The Yachtwork patented production. USD. This is far less cost than any shop is going.
Beneteau, Jenneau, and many. For the rest of marine engines read the instructions below and. SIX STEPS TO ALTERNATOR II 1.
Design and planning. Mounting a second front pulley. Making a base plate. Building a bracket from the base plate.
Installing a belt tensioning device. Bolting in the alternator. DESIGN AND PLANNING Start the design process by taking an alternator in hand and. There should be 1. Face the alternator aft and you have six more possible locations.
Hold the alternator in all 1. Pick the best two or. Choose a mounting. Look for access, wire runs, mounting bolt holes in the engine. MOUNTING A SECOND PULLEY We need to spin the second alternator from a second drive pulley. Your engine may already have one. First, choose a pulley size.
For a typical 3. 0 to 7. I’ve experimented with larger pulleys (up to 2. Conversely, if the pulley diameter is less than 1. I often. have to run the engine up to 1. If in doubt, duplicating the original pulley size is usually.
There are two easy methods to fit a spare pulley to the front. Have a machine shop make the new pulley; or,2. Modify an existing pulley. METHOD 1. A machine shop makes the new pulley, the simplest but most expensive.
The machine shop will need the bolt pattern and centering ring. If. you can take the measurements from the manual, the machine shop. If you have to take the measurements. Be sure to scrape away any old.
Note: If the alternator is to produce more than 8. You’re pushing the limit with a single. METHOD 2. Buy an “off- the- shelf” pulley at your local hardware. You can even use an old car’s sheet metal“stamped”. The machine shop will combine the pulley onto a centering. This option has the advantage of knowing the pulley face angles.
It does not take much angle. Belt dusting is the major problem. Twist, misalignment, rough. Commercial pulleys help solve this issue.
METHOD 3 For emergency and bush use only. The third method I have never tried, but other mechanics swear. I include it. here for your perusal. Go to the local hardware store or wrecking yard and buy a steel. Lay out the bolt holes and drill them as best you can. Bolt the new pulley to the old pulley and keep the bolts snug. Turn the engine over (without starting) while holding.
Find the pulley’s. Keep this up till you have.
Tighten the bolts. If you stopped now the pulley would quickly slide out of center. To prevent. this you drill two or three holes through the new pulley and into. Tap a roll pin into the holes. The roll pins hold.
I have never had to resort to this method, and if you do all. I can say is “hope for the best”. MAKING THE BASE PLATEThe base plate is a steel plate that gets bolted to the engine. The bracket is typically welded to the base. Look for flat areas on the side of the engine block near where. You want the plate to cover. Cut a piece of steel to cover the bolt holes.
Using 6mm plate. is the minimum – 8mm is better. Test fit the piece of steel. If it all fits and covers the. Marking where the holes are to be drilled can be challenging. Here’s. an easy trick – it’s what I call the “sneak. Leave just enough bolt thread (the sharpened point) showing so.
Lay the base. plate in the exact final location. Now for the tricky part –. Once marked you are ready to drill the. Remove the bolt/punch and shift it to a new hole. Fasten the. base plate (with a bolt through the newly- drilled hole) in position. Another sharp tap, remove the plate and drill the new hole. Repeat. this process until all holes are drilled.
This method is fast. If you make the base plate. BUILDING A BRACKET The bracket is the metal frame that holds the alternator, allowing. I like to use a 5.
Cut two ears and weld them on the flat bar at. You should now have a base plate. They may need to be connected with a. It’s usually the simplest to weld.
ALIGNMENTTo find the correct alignment for the alternator, lay a wooden. Let the rod find. You can now simply lift the rod up and down. Reverse the procedure until the slave pulley is pointed. Remove all parts and tack the strut into position. Replace and see if it all fits.
If it does it’s time to. Use this dowel rod method anytime you want. MAKING A BELT- TENSIONER Turnbuckle tension arms are an easy solution for making an alternator.
If you were making a conventional car- type. Many boaties fit this turnbuckle. Begin with a half- inch or larger open barrel turnbuckle, and. Cut the center out of the barrel, leaving leavening 1. Weld the barrel back together.
Put the studs back in place and. Weld a flat plate to the end of each stud, drill a hole in the. AUTO TENSIONING ARMAn automatic tensioning arm is another easy solution for a DIY. You can buy a “rasta” or Love.
Joy arm for automatic. Check out http: //www.
The device costs about $1. Simply mount the roller inside the. In the. photo above, the pulleys turn clockwise. Adjust the tension and.
The second advantage of using a “rasta” or Love. Joy. tensioning arm is the alternator does not have to rotate away. This may mean a lot if you. You simply mount the alternator. STOP ENGINE BEFORE TURNING “OFF”Ever notice what battery switches have printed on their faces?
We all know not to disconnect the batteries while the engine is. An alternator diode would fail – and that’s not good. The reason is buried in Ohm’s Law which lays out the relationship. An alternator’s total power. A typical high- output alternator. V – 1. 00 x 1. 4 = 1.
If we had a 2. 4- volt system, the alternator would be producing. So, when we have an alternator producing 1. But the load (or current or amp draw) just. Ohm’s Law tells us 1. In other words, the voltage inside. That’s the shortest. Pop! The diode shorts.
Quickly switching the batteries back on might save the situation. The boat owner may see the output. A typical complaint. My 1. 00amp alternator is now producing. This is because the alternator stator is really three- phase.
Since only the diode was ruined, each phase of the stator is still. If all three phases of the alternator are still. The “lost” 3. 3amps are still being produced, but they’re.
And. un- rectified means alternating current (AC) is entering your DC. This is bad. At the same time that we are charging at 1.
DC, we are also sending a battery- destroying AC “charge”. And because the boat’s. AC, the owner has no clue. Those 3. 3 AC amps are destroying the boat’s battery bank.
DIODE TESTTo check whether your alternator has a shorted diode you can. AC/DC “clamp. amp” meter. Switch the meter to DC amp and read the charge. Switch the meter to AC and we should see three or four amps. A reading half of the DC charge rate indicates a bad diode. For. example, if we were to see 6.
DC and 3. 3amps AC, this would. Although not as accurate, we might also take a high- quality digital. We should see around 1.
AC and we should. Reading 1. 4 volts AC could also indicate. Adapted from Scott Fratcher’s How To Make Money With Boats. Add. a PTO to any engine. Check hoses for cracks. Basic Fast Flow Emergency Bilge Pump Kit$5. USD plus shipping.
