Rebel XT Problem Firing Novatron Strobes

[whitworth photography]

This past weekend I tried to use my Rebel XT with a set of Novatron

strobes on a power pack owned by another photographer.

 

I use a Wein safe sync as a hot-shoe adapter, so initially I tried

connecting up that way. I wasn't able to fire his strobes and was

told that some of the Wein syncs aren't compatible with Novatron

power packs.

 

I then used a standard hot-shoe adapter, but still was not able to

fire his strobes.

 

Also worth noting, I have my own set of strobes which are Alien Bees

and was also using a 420 EX that day. I didn't have any problems

with either of those setups which were used after I tried using the

Novatrons.

 

I did some searches and found a post where somebody was having

troubles with Novatron strobes pre-firing due to the 10D E-TTL pre-

flash. The XT has E-TTL II and I was thinking maybe the Rebel XT

flash system may be incompatible with the Novatron power pack?

 

Also worth noting, I had the camera in manual mode fixed at 1/125 and

F8.

 

Thanks for any guidance you guys can provide.

I used to use older novatrons with a 300D. Canon sync curcuits are polarized, try flipping the HH plug around on the pack.
