<div dir="ltr">Thanks for all the info. A bad 3 wire connector was what started all this and a new one fixed my immediate problem. A couple of Denso, single wire types, are on the way here as well as assorted brackets and a 4" pulley. The good news is I don't need to scramble to make my next 3 events (just make sure the battery charger is in the new camper) and hope to have the reengineered parts installed in time for PittRace.<div><br></div><div>thank you </div><div><br></div><div>mike h</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Mon, May 19, 2025 at 5:26 PM R.

<p>While on the subject of alternators ...</p>
<p>Once upon a time, a couple decades past I purchased an alternator conversion kit from a Morgan parts house for my TR3. About 7 or 8 years ago it failed while I was near Laughlin NV. I had a local shop fix it. They replaced my 3 wire alternator with a single wire system that used the wire going to the idiot light to charge the battery. For the past few years the alternator output didn't start charging until I hit about 2000 RPM and didn't go to a full 15V charge unless the engine was turning 3200 RPM or better. The 2 wire connector on the side of the alternator has a wire they never connected to anything.</p>
<p>I've been tempted to replace the alternator with a 3 wire system that starts charging when it is supposed to but have no idea which alternator to buy.</p>
<p>I never wrote down the number or ID of the alternator I purchased from the Morgan shop and forgot which shop it was. I've only worked with Delco 10 & 12SI alternators and what's in there appears slightly smaller.</p>
<p>So what is a good 3 wire alternator that fits a TR3 bay? I have an electric fan so I would guess 60 AMPS would be more than enough for the fan, headlamps, and a pair of aux lamps.</p>
<p>Suggestions?</p>
