The shop tested the alternater they sold me, it'll do 75 amps. My present amp meter is a 60.It had a 10 gauge wire to alt and 12 gauge to the master switch terminal.I understand that the original alt was small but it just barely kept up. I finaly had it tested and it was hardly working.Not that many miles,maybe the small wire is partily to blame. I've started with the #4.but it's just laying on top of the engine now .It is difficult to feature that heavey wire coming in and out the fire wall ,to and from the gauge. All gauges are SW and I'm finding it hard to find anybody other than a distributer who still will have to order it and has no knowledge.SW meters aren't in any of the stores I've been in.I ordered a new speedo three years ago and a vacum gauge a year and a half ago.I went into that store today and they can't find a SW catalog"come back next monday and maybe ***** can find the catalog".The SW website doesn't show pictures of the gauges just series Like I allready knew .
So it is a 100 amp meter or go to a voltmeter and try to make it look correct.
What does the shunt do?
