SUBJECT: JUNCTION BOX ASSEMBLIES FOR TEST TANK USE
In order to properly test electric starting engines in a test tank, it is necessary to use the proper junction box, wiring assembly, etc. designed for the specific engine being tested.

378233 Junction box assembly - for 1961 - 40 & 75 H.P. engines RDS thru V4SL $15.00 each, net
378234 Junction box assembly - for 75 H.P. alternator engines V4A & V4AL $36.00 each, net
These junction box assemblies are complete as shipped with new engines. Deviations will not be made, neither to supply other than complete assem- blies, nor to further alter the special prices quoted above. These assem- blies are for test tank use only and are not to be offered for resale.
The quoted special prices will be honored only when assemblies are order- ed on the enclosed order blank.
