<p>While a solid-state regulator has no moving parts, and may
provide tighter regulation than a classic old-fashioned mechanical
regulator, keep in mind that the components on the solid-state
circuit board are subject to shock, vibration, and temperature
extremes.</p>
<p>The substrate itself (the printed circuit board) is also subject
to these factors. Under the bonnet is a hostile environment for
electronics.</p>
<p>From the photos, it's clear the integrated circuits are
small-outline surface-mount devices. The pins on these ICs are
very small and on a fine pitch (close together). Also, ICs are
rated in three categories: 0-70 degrees C, -25 to +85 degrees C.,
and -55 degrees C to +125 degrees C. <br>
</p>
<p>These three categories are dubbed "commercial," industrial," and
"military," respectively. Which temperature-range devices are used
on these boards?</p>
<p>Also, notice the sub-board, which looks like a plug-in. Separable
interconnects are also subject to failure due to oxidation and
vibration.</p>
<p>Just some thoughts.<br>

<p class="MsoNormal"><span style="font-family:"Trebuchet

input. I received the diagnosis on my generator Friday, and
I’m going to proceed with having it rebuilt. I’m also going
to contact Dean Sprague of Vintage Mecha-Tronics (<a

moz-do-not-send="true">www.vintagemechatronics.com</a>)
this week regarding their electronic regulator. The quality
of the Lucas electronic unit is suspect based on the
comments received, which are echoed in the information on
Mecha-Tronics website.<o:p></o:p></span></p>

<p class="MsoNormal">In my opinion, whether you need more
current supply or not isn't the primary reason to go with an
alternator or an electronic voltage regulator. Either will
provide a more stable voltage to the system, which is good
for anything electrical including points and coils,
overdrive solenoids, fuel pumps and especially electronic
ignitions like pertronix etc.. If you have an electronic
tach like on the later cars, it will be more stable too and
happier with a cleaner power source. I would use the
electronic regulator if you decide to rebuild the generator.<o:p></o:p></p>

the higher output of the
