Delco Remy Expands Use of Smart Magnetic Switch in Starters
Work smarter, not harder, says Delco Remy. That's what the
company's automotive starters with its Smart Starter technology
do, leading Delco to add the feature to many of its high-volume
aftermarket starters.
The new starters have Delco's Smart Integrated Magnetic Switch
(IMS) plus Integrated Overcrank Protection (IOCP). In addition to
updating the original Smart IMS part numbers to the newer Smart
Starter ones, the company is adding more part numbers for the
aftermarket. The protective feature has been added to seven of
the most popular Delco Remy starters including for brands such
as Paccar, Navistar, International, Caterpillar, Detroit Diesel and
Cummins.
" The Smart Starter is an ideal solution if you have customers or a
fleet population with repeated warranty claims due to operator error, "
says Brian Koehlinger, Senior Sales Manager. " It's designed
to eliminate the six most common failure modes that are often
due to operator error. That means it also prevents costly repair
or replacement costs. "
The technology protects against common failure modes. For
each, there is a protection feature in the Smart IMS to counter
it and prevent the failure from occurring. The Internal Magnetic
Switch Solenoid (IMSS) is a patent-pending one-wire design integrated
inside the solenoid. Input current is compatible with an
engine control module and protects it from voltage spikes while
withstanding high temperatures. Because of its integration inside
the solenoid, it is protected from corrosion caused by environmental
factors and damage from vibration issues. Installation is
simpler since no additional wiring or mounting bracket is required
and corrosion is reduced with no connection points.
But don't remove the integrated magnetic switch, Delco cautions
designers and installers, for both performance and safety reasons.
The benefit is that the IMS provides a higher current draw
for the motor by reducing voltage drop and controlling battery
current. This ensures the solenoid receives the maximum available
voltage in any starting condition. Removing it would result
in significant control circuit problems, also void the warranty.
If an IMS is part of a gear reduction starter, it should never be
removed, bypassed or uninstalled, says the company, and In the
event of replacing a unit with an external magnetic switch, there
are options for accomplishing the task.

Always designing its aftermarket products with the needs of dealers
and service outlets to minimize their parts inventories, Delco
Remy's 39MT gear reduction starter features a rotatable flange
for compatibility with replacement of many original equipment
models. The Integral Magnetic Switch is rotatable, too, into six
different positions. See www.delcoremy.com.
