Hi CAT3K.
I came accross this forum ( a great resource ) when Googling for some up-to date info on a pile of RC cars and equipment etc. left in my loft, belonging to my sons who used to race them over 20 years ago.
In answer to your query re. Barracuda charger, we also have one, I have a copy of the instructions ( about 8 pages ) which is now a bit tatty.
When I get a free moment I'll type them up and post them on here if that's OK with admin.
I'll also post a picture of our Barracuda which, at the time, was bought second hand.
One great function of the charger they used to advantage all those years ago was that it helped to determine which was the best pack to use for various types of races, the charger would give the battery capacity in kj, monitoring a pack from new would enable them to determine that there was a possibility of a pack / cell failing.
Though not of much use for modern racing, LiPo's etc it's great for retro-racing with the old NiCads.
By the way, the terminal ports on the side of the charger are as follows:
Black and Red, positive and negative input from a 12v car battery.
The grey one is a temperature probe.
The two yellow ones are to connect to an external resistor to discharge the pack.
As well as being a simple charger it can also discharge and cycle, charge/discharge, packs to keep them healthy and keep the dready NiCad disease, memory effect, at bay.
Hope this is a bit of a help.
I'll pop back on the forum when I get a chance, it looks like the "flleet" is going to be restored, grandchildren have seen them.
The main part of the fleet is two ProCats, two Cougars, two Mardave Marauders ( with gummed up engines ) and their first ever cars two Mardave Meteors.
