I purchased a used Hyster E30XL 36 volt electric around 4 months ago
monotrol control,, It has been working fine (light use) and now I am having an issue of intermittent loss of forward and reverse.
this occurs after a short time of use, (lift is not effected). If you wait 4 min or so it will start working again, but will reoccur in what seems like a shorter amount of time. on inspecting under the cover I found that a PO had monkeyed with the 2 terminal blocks going to the motherboard (siliconed in place) as if the was an issue with a loose connection, took it apart & cleaned it up, checked mother board, no obvious burn marks or cracks,, put it back together (seems like connectors are connecting) and same issue. The relays continue to click during issue..
I sourced a new (rebuilt) mother board @$300 but no idea if that would b a fix,, any advise would be greatly appreciated
