Altinator failed.
Comming back from a cruise today and my alt failed. Got a 82 with a standard 70 amp equiped alt i believe. Just wondering what is the best way to go as far as amp output (higher than stock) with the stock wireing? I do have a direct feed to my alt via a crane hi-6 msd box.

lots of high putput alternators availabe from various sources but you can also take your current alternator into a local shop that rebuilds them and if you want they can rebuild it as a higher output unit about as easily as they can rebuild it as stock.
Not sure about where yo live but a local place near me that does alternators and starters usually gets them done in one or two days and the cost is typically lower than the cost of buying a new unit.

a 70 amp alt is fine unless you have added a significant number of items to increase the electrial load on the system and increasing the alternator output isn't going to solve a dim headloght problem. The problem in general is that the way the electrical system is designed and set up.
By using relays to take the load off the system and put it onn dedicated relays can help greatly and will make a much greater improvement that trying to upgrade the alternator.

If you're running a serpentine system that was designed for a CS130 you may have to futz with the bracketry a bit to accomodate the 144's 5/8" wider bolt spacing.

Changing the pullies is a snap since the shafts are the same, and your old alternator has the pulley and the new alt will have the fan. Use the same retaining lock washer and jam nut. Put the alt in a vise, put a strap wrench around the pulley and use an impact the work off the nut. Usually they just come right off, but teh stuborn ones will be a bit tougher.

My 140 amp CS alternator failed on my two weeks ago in the burnout box, the plastic fan exploded and broke my hood. I saw something fly over my head but I thought it could have been a chunk of rubber. Pulled into the pits and noticed a 3" section of paint missing from my hood......
Next day I measured the pullies, it was only spinning at 20,000RPM!

Yeah I don't think the metal fan will grenade like the plastic one. Regardless...bummer about that hood. You think you can repair it or are you in the market for a new hood too?

Hmm...makes me wonder what's lurking under that cracked up hood of yours. Could be something...MEAN.
