Adjustment dials must be disabled, sealed on Crane ignition boxes in 2017

first_imgVINTON, Iowa – IMCA will require four ignition boxes available from Crane Ignition to have adjustment dials disabled and permanently sealed when used in sanctioned Modified, Late Model or Stock Car competition in 2017.Those ignition boxes are:Crane HI-6RC ignition part number 6000-6700;Crane HI-6N Oval track ignition part number 6000-6410 (Weatherpak Plug);Crane HI-6N Oval track ignition, part number 6000-6412 (Deutsch Plug);and Crane HI-6RN oval track ignition, part number 6000-6750 (Digital).“These ignition boxes all have adjustable RPM limits and, as a result, an issue that allows them to operate at a different RPM limit than what the box is physically set with the adjustment dials,” explained Dave Brenn, IMCA’s executive director of competition. “For 2017, these existing Crane ignition boxes will still be allowed but must have the adjustment dials disabled and permanently sealed, effectively making the box operate as a preset RPM limited box.”“After choosing the desired RPM limit, the box must have a cover plate permanently sealed with an epoxy-type adhesive over the dials,” he continued. “Silicone or other non-permanent adhesives will not be allowed.  Failure to seal these ignition boxes will result in an immediate disqualification when used in any IMCA event.”On Dec 31, 2017, all four products will be removed from IMCA’s approved ignition list.last_img
