BobsZTwins Posted April 3, 2004 Share Posted April 3, 2004 I have a Scarab conversion, done back about 1980 that, believe it or not, is still using the Hitachi LT150-10 37.5 amp unit! I'd like the upgrade to a 3 wire GM style unit but the JTR manual is a little short on info for the 260 wiring. I want the 3 wire for the voltage sensing and to power the charge light in the voltmeter (I swapped the ammeter out a while ago.) In the 260 there's the voltage regulator as shown in the JTR manual but there's also what the wiring diagrma calls a Shunt under that plus a box with 2 Fusible Links on the firewall. Can all that be eliminated with an internally regulated GM type alternator? The reason for the alternator change is I want to go with an elec fan like the Taurus 2-speed unit. Has anyone figured out the wiring/relays to use both speeds on those fans so you don't have to use manual switches? I did a search on the archives but the links in the posts don't work anymore, maybe a by-product of the site upgrade. Thanks for any advice!
